Creating two seperate networks with 2 time capsules?

So i currently have two time capsules. The first one is bridged with my dsl modem and is acting as my internet gateway and backup for my main imac and macbook which are connected wirelessly as well as a file server with addition external harddrive connected via usb.
I want to connect an additional timecapsule via ethernet and use it to create a seperate wireless network that allows my guests, kids macbook and any of his hooligan friends to connect. The second time capsule will allow my kid to back his macbook up. I dont want this network to be able to access my up stream network with my main imac and macbook because I will not be issuing poeple access to it except myself and will lock it down with MAC address filtering.
I am worried as my kid or any guests I allow to access my network can or will be able to reach my main computers and I want to prevent that. Is this possible with two time capsules?

Now if this setup will reduce the NAT doubleing issue on the ps3, xbox and apple tv's thats good?
Should work as long as you understand that these devices are connecting to the Guest Network on your "main" TC. How well wireless will work going through all the obstructions is open to question.
You will also be sacrificing half of the bandwidth on your "main" TC when you enable the Guest Network feature.
There will still be a Double NAT for devices that are connected to TC #2.
My next question is how do I allow everyone to see my ethernet printer? Plug it into TM#2 ethernet port?
Not sure what you mean by "everyone".
If you plug it into the TC #2 Ethernet, devices on the TC #2 network will be able to see it, but not devices on the "main" TC network.  Reason....TC #2 is on a different subnet than TC #1......unless you want to setup TC #2 in Bridge Mode.
If it were me, I would password protect all computers and devices on the "main" network, except the printer. Then, connect TC #2 in Bridge Mode and call it a day. 
Users on TC #2 will be able to "see" other devices on the TC #1 network, but not connect to them unless they have the password for the device.

  • Is it posible to create a lan network with time capsule?

    I need to know if it´s possible to conect various computers via time capsule WI-Fi.
    At least I will like to conect my MbooPro that is using ethernet to conect to Time capsule Internet etc...to myMBAir, without going through the web.
    The idea is to use DropBox using it´s Lan connectivity.
    Oriol

    Yes, it is possible to create a wired/wireless LAN with your Time Capsule (TC) without having to have the TC connected to the Internet.
    The TC would not get a Public IP address, but it would have a Private IP address of 10.0.1.1 ... and it would be providing wireless clients connected to it with Private IP addresses in the 10.0.1.2 - 10.0.1.200 range.
    The following would be the basic configuration settings to run the TC in "standalone" mode:
    AirPort Utility > Select the TC > Manual Setup > AirPort > Wireless
    o Wireless Mode: Create a wireless network
    o Wireless Network Name: <enter a desired Network Name or SSID>
    o Radio Mode: <leave the default or select a desired radio mode>
    o Channel: Automatic
    o Wireless Security: <select the desired wireless security type>
    Internet > Internet Connection
    o Connect Using: Ethernet
    o Connection Sharing: Distribute a range of IP addresses
    Internet > TCP/IP
    o Configure IPv4: Manually
    o IP Address: 10.0.1.1
    o Subnet Mask: 255.255.255.0
    o Router Address: 10.0.1.1
    o DNS Server(s): <leave blank>
    o Domain Name: <leave blank>
    Internet > DHCP
    o DHCP Beginning Address: <leave default or change to a desired starting address>
    o DHCP Ending Address: <leave default or change to a desired ending address>
    Advanced > Logging & Statistics
    o Allow SNMP (unchecked)
    Your TC will still report a number of errors. These can all be safely ignored. To stop the TC's status light from flashing amber in this configuration, you can use the AirPort Utility to disable them.

  • Two WiFi Networks with Time Capsule

    After installing TC (attached to an existing router), I seem to have two WiFi networks. is this normal? what should I do?

    Thanks for the clarification. 
    In general, unless you really need two wireless networks, it is a good idea to turn the wireless function off on one of your routers to reduce the chances of wireless interference that might occur between them.
    If you notice no problems running two networks, you can leave both "on" if you want. In the future, if you notice diminished wireless performance, you probably will need to turn off the wireless function on one of your routers.

  • I'm trying to extend my wifi network with time capsule but it can't find the existing wifi network

    I'm trying to extend my wifi network with time capsule but it can't find the existing BT wifi network even though it is there with a good signal strength. The Time Capsule is connected to a Netgear router via ethernet.

    You will need to start over on the setup of the Time Capsule as follows:
    Disconnect any Ethernet cables that might be connected to the Time Capsule, but leave it powered on
    Hold in the reset button on the back of the Time Capsule for 8-10 seconds and release. The reset button is located next to the AC power socket.
    Allow a full minute for the Time Capsule to restart to a slow, blinking amber light
    Connect the Ethernet cable from a LAN <--> port on the Netgear to the WAN "O" port on the Time Capsule.  The Ethernet cable must remain connected at all times.
    Click the WiFi icon at the top of the Mac's screen
    Look for a setting of New AirPort Base Station
    Click on Time Capsule
    The example below shows an AirPort Express. You will see Time Capsule on your screen.
    That will get the setup wizard going. It will take a minute to analyze the settings, then display a screen that looks like this, except you will see a picture of the Time Capsule
    Network Name..........Type in the exact name that the Netgear wireless is using
    Base Station.............Type in a name that you want to call the Time Capsule.  Use something short and simple. Mine is TC, for example
    Password..................Type in the exact password that the Netgear wireless requires
    Verify.........................Verify the Password again
    Click Next
    The setup wizard will configure everything for you automatically.  When you see the message of Setup Complete, click Done.
    That's it.  Now you have one big "extended" network.  Technically, this is called a "roaming" network.

  • How can i extend a wireless network with time capsule

    How can i extend an existing wifi verizon wireless network with time capsule? the router is connected on the bottom floor. want to boost the signal to a home office on the top floor, four flights up. connect time capsule via ethernet cable to iMac on 4th floor? Do I have to start a second wifi network or can I set it to just boost the one I have? thank you

    How can i extend an existing wifi verizon wireless network with time capsule?
    It all depends on what you mean by "extend".
    If you plan to "extend" by connecting the Time Capsule to the Verizon router using a wired Ethernet cable, this can be accomplished.
    If you were hoping to connect the Time Capsule to the Verizon router using wireless only, unfortunately the Time Capsule and Verizon products are not compatible for that purpose.
    Check with Verizon to see if they offer an "extender" or "repeater" that could be located very close to the Time Capsule.
    This would provide both more wireless coverage and also allow you to connect the Time Capsule using an Ethernet cable from the "extender" or "repeater".

  • Creating wireless network with Time Capsule

    hi, I just have couple of questions before installing the time capsule;
    so far I have been using cable DSL modem, so my question is - is it possible to set time capsule as a wireless router, or does time capsule still have to be connected with DSL modem and then act wiresly with iMac?
    I was thinking if i could replace cable DSL modem with time capsule
    thank you

    The Time Capsule has to be connected to your DSL modem. Otherwise you won't be able to connect to internet.

  • Problems wirelessly extending 5Ghz network with Time Capsule

    Summary:
    My Time Capsule wirelessly extends a 5Ghz "n" network provided by my Airport Extreme, but the Time Capsule frequently fails and stops providing Internet access to connected computers. I'm not sure if the problem is with the Time Capsule or with the Airport Extreme it's connecting to.
    Setup:
    Airport Extreme (dual band) connected to cable modem. It provides a 5Ghz "n" network and a 2.5Ghz "b-g-n" network. This is in the bedroom.
    Time Capsule (non-dual band) joins the 5Ghz network and extends it. This is in the office, maybe 40 feet away, line-of-sight. There is a laser printer connected to the Time Capsule via ethernet.
    My MacBook is set to join the 5 Ghz network, and since it's in the office, it ends up joining via the Time Capsule. This is the desired behavior, as connecting through the Time Capsule seems to result in the fastest possible backup speed.
    There are no wireless devices, such as cordless phones, in the house. The microwave is NOT in use when the problems arise.
    *The Problem:*
    Frequently, the MacBook loses its Internet connection, though it is still connected to the 5Ghz network through the Time Capsule. When this happens, it can only see the Time Capsule it's connected through (and other devices that are connected to it) but no other devices on the network.
    When this happens, other devices that are connecting to the 5Ghz network through the Airport Extreme can no longer see the Time Capsule or any devices connected to it, such as the laser printer or my MacBook. This includes the living room computer, which has never been able to complete a backup due to this problem.
    The Time Capsule's and the Airport Extreme's indicator lights both stay green.
    If I change the Macbook's connection to the 2.5Ghz network, it can see the devices connected to the Airport Extreme, but can no longer reach the Time Capsule.
    *Unsuccessful Solutions:*
    This was happening in a previous incarnation of the network, when I had a non-dual band Airport Extreme providing the main network, the Time Capsule connected via 5Ghz, and an Airport Express connected via ethernet to the Time Capsule to provide a b-g network.
    I replaced the Airport Extreme with a new dual-band unit to simplify the setup, but it did not solve the problem.
    Since the Time Capsule seemed to be the weak link in the network, I reported the problem and got the unit replaced, but the problem still persists.
    I've reset both the Airport Extreme and the Time Capsule to their factory settings numerous times, and set them up again from scratch (no imported settings). I've gone in and made sure that there were no WDS settings leftover from the earlier configuration, as the 5Ghz network does not need it to extend itself.
    *Plea for help:*
    Is anyone else experiencing a similar problem?

    Update
    The other day, I modified the setup so that the Time Capsule doesn't extend the wireless network wirelessly, only through Ethernet (so the attached printer will work, but the computers will connect directly to the AEBS. The Time Capsule stayed connected long enough for me to do a full backup (125GB) from the downstairs computer.
    I thought I had it "solved" (though extending the 5Ghz network would be preferable so the office computers can have faster backup speeds.)
    But yesterday, I went to print to the Ethernet-attached printer, and it got only one page out before it disappeared off the network again, and the print job failed. I noticed it did it again, today.
    So the problem is not tied to wirelessly extending the network.

  • IPad2 in network with Time Capsule

    will i be able to use the time capsule for a iPad as a external memory and transfer file from one to the other?

    No, the iPad only connects to the internet sharing option of your network router (Time Capsule) through wifi. All other features of your router can't be accessed by your iPad. I have both also, so it would be nice. Try making that suggestion to Apple in the support section of the website. Who knows? We might get lucky. If this answer is satisfactory, please consider marking it as answering your question.
    Thanks

  • Unable to Create Guest Network with Time Capsule

    Time Capsule version: 7.6.1, AirPort Utility: 6.0(600.92), Cabel Modem Ambit U10C018, iMac w/ Mac OS X (10.7.3)
    I have the Time Capsule installed as the only router. The Network settings, Router Mode is: DHCP and NAT. I am unable to find any tab or button for "Advanced" that will allow me to set up a guest network.  I am pretty sure that cable modem does not function as a router because when I changed the Time Capsule to Bridge I was unable to make any wireless connections. 
    Any help woudl be greatly appreciated, but I will be away from the computer for the next 3 hours.

    We will assume that your Time Capsule is not one of the 1st Generation models, which did not have Guest Network capability.
    But, if your Time Capsule is a few years old, or you purchased it from another user....you may have a single band version of the product....which cannot offer the Guest Network option.
    If your Time Capsule has the capability....here is how to set up the Guest Network
    Open AirPort Utility and click on the Time Capsule icon that appears
    Click Edit in the next window that appears
    Click the Wireless tab at the top of the window
    Enter a check mark next to Enable Guest Network
    Edit the name of the network as you wish
    Select Wireless Security...either WPA2 Personal or WPA/WPA2 Personal would be good
    Enter a password for the Guest Network and verify
    Click Update at the lower right

  • Troubling extending wireless network with Time Capsule and Airport Extreme

    I am trying to set up and extend a wireless network in my house, but it’s not working right. I have two Airport/Capsule units in the house:
    2TB Time Capsule (Dual-Band II)
    1 Airport Extreme (Dual Band)
    I have the Verizon Fios router as my gateway to the internet, and also as my DHCP server. I have also tested the ethernet ports in my house to verify that they work, and that I can get a DHCP-issued IP address.
    Now, my Verizon router has WiFI, and it’s still on. I am not using it though except to troubleshoot. So far as I understand, this should not cause a problem.
    Base station setup
    So I setup the TC to Create A New Wireless Network, on the ethernet network it’s on (Dlink switch plugged into Verizon router). I set it up in Bridge Mode (as opposed to having it dole out IPs, since the Verizon router does this already). The TC gets a valid IP, and my wireless device connect to it without a problem. I have checked “Allow this network to be expanded” under Wireless settings.
    Extended station setup
    The AE Dual-Band is plugged into the Ethernet, and is reset to Factory Settings. I name it “Airport Extreme 2” and I chose “I want Airport Extreme to join my current network.” The other two options are: “I want to create a new wireless network” and “I want to replace and existing base station or wireless router with Airport Extreme.”
    I chose to “join,” I select “I want to connect Airport Extreme to my network using Ethernet to extend my existing wireless network.” The other options are to disable wireless entirely, or to “wirelessly join my current network.” On the next page it asks me to select the device or network that the Airport Extreme will connect to using the Ethernet. I set it to the Time Capsule.
    Results:
    Access near the Airport Extreme 2 is incredibly slow. Speedtest shows I am getting less than 1Mbps. Worse yet, my mail client won’t connect. It just times out.
    What I had hoped was that the AE would connect via Ethernet to the network, and just bring the wireless network to the other side of the house. Instead it almost seems as though it is just re-amplifying the TC’s signal. Otherwise, why is performance so bad?
    Thanks to anyone with some insight here!

    Hello Kennuff. Welcome to the Apple Discussions!
    Since you have the ability to connect all of the routers by Ethernet, there is no need to configure the Time Capsule (TC) & 802.11n AirPort Extreme Base Station (AEBSn) for a dynamic WDS (aka, extending a network). This option is only when the routers do NOT have an Ethernet connection between them.
    Instead, you want to configure the TC & AEBSn in a "roaming" network. I suggest starting by performing either a "hard" or "factory default" reset on both.
    Next be sure that both the TC & AEBSn are on the same Ethernet subnet coming from the Verizon-supplied router.
    Configure the TC & AEBSn as follows:
    AirPort Utility > Select the TC or AEBSn > Manual Setup > AirPort > Wireless
    o Wireless Mode = Create a wireless network
    o Allow this network to be extended: <not checked>
    o Radio Mode: <leave the default or if you require a specific mode make sure both routers are configured the same>
    o Wireless Security: <configure both routers the same>
    AirPort Utility > Select the TC or AEBSn > Manual Setup > Internet > Internet Connection
    o Connection Sharing = Off (Bridge Mode)

  • Extend FiOS wireless network with Time Capsule

    I have a FiOS wifi router and a 1TB TC (with latest firmware 7.6.3). I'd like to extend the wireless network to cover some dead zones. I've run ethernet from the LAN port on the router to the WAN port on the Time Capsule, and it's getting an IP and internet connectivity. However, when I follow the Apple instructions to extend a wireless network, I get the warning error "unable to extend network" and the flashing orange light. I've confirmed the SSID and password are correct and match the FiOS SSID and password, and I've confirmed that the TC is in bridge mode. I've also logged into the FiOS router and confirmed it's assigning IPs to the wired and wireless componets of the TC, and recognizes the wireless is in bridge mode. Any suggestions?
    I've got it working currently as a separate SSID, but it's just a pain to have to jump from weak-network1 to TC-network2 whenever I'm in a dead zone. Thanks in advance!

    Check to make sure that you have the TC configured to.....
    Create a wireless network  (not "extend".....as that is only used for wireless extension and you are using Ethernet)
    Use the exact same wireless network name (SSID) as the FIOS router
    Use the exact same type of wireless security that the FIOS router is using (Make sure that this is not WEP)  It should be WPA2 Personal or WPA/WPA2 Personal.
    Same wireless password as the FIOS
    Bridge Mode configuration
    Unless everything matches up correctly, you will have two separate networks that require two separate log ons.
    Configured correctly, you will have a "roaming" network. Your Mac will automatically switch over to the wireless access point with the best signal quality as it moves from one area to another.

  • Slow network with Time Capsule

    Hi There!
    We have a network at home consisting of a Time Capsule (to provide wireless to the house as well as to hold all of our iTunes content and use as a file server), two Mac Pro towers, a MacBook Pro, an iMac, and two Windows-based notebooks, and an Apple TV. We are NOT using the Time Capsule for backup.
    The problem we're having is that the network is incredibly slow. Trying to copy a large file over the network can take hours when it should only take minutes. And we can't stream shows/movies in iTunes from the Time Capsule because it pauses every one or two seconds to catch up. We also have business grade cable modem service but we can't do iChat videoconferencing without the audio/video completely dropping.
    We tried purchasing an Airport Express to extend the range of the signal (and even purchased a second one!) but those didn't help, either. The firmware on all devices it up-to-date. And the network is closed (no one is leeching).
    Are there any tools, either built in to OS X or another source, that can help us diagnose what's wrong with our network? What other things can we try to diagnose the slow network?
    Thanks!

    First of all, be aware that the more devices you connect to a wireless network, the slower it goes. In addition, if you have devices that only work at B or G speeds, all devices on the network slow down to the slowest device.
    For example, when you have a 300mbps N device and a 11mbps B device connected to the same network, they'll both go at a maximum speed of 5.5mbps. You are limited to 11mbps because of the B device and then further limited to 5.5mbps because there are two devices sharing the total (11mbps) bandwidth.
    As far as testing out your current connection, try these:
    1. On a mac, you can hold down Option and click on the airport/wireless icon. This will show transmit rate and other information. The maximum transmit rate for N devices is 270, G: 54, B: 11. If the transmit rate is very low, this indicates a poor wireless signal
    2. Change the wireless channel used by your time capsule to something else. Try them all to see what gives you the best wireless signal
    3. In the airport utility, select the time capsule, go to manual setup, go to advanced, click on Logs and Statistics, then click Wireless Clients. This shows the transfer rate, noise, and signal for each device connected to the time capsule.
    4. Download iStumbler. This mac application will show other wireless networks in the area and what channel they're using. It is typically not good to set your network to use the same channel as others in your area.
    5. Download some sort of application that shows transfer speeds (like iStat Pro). Test transferring large files between computers to see how fast it goes with different setups.
    There's a few things you can do to improve wireless performance when bogged down with too many devices:
    1. Turn off any wireless devices not in use. If it's on, it's using bandwidth space even though it's not transferring data.
    2. Use multiple routers or a dual-band router to create separate networks. For example, you can make the time capsule make a 802.11N-Only network which will only the new N devices will connect to. Plug an express into it and make it create another network (G-only or B/G-only). Keep plugging in additional routers and make new networks as needed.
    3. Replace older B/G devices with N devices if possible.

  • Extend wireless network with Time Capsule

    I have a dual band Time Capsule in a two story house. The TC is upstairs, and I have an Airport Express downstairs to extend the wireless network. However, the speed is very slow downstairs. I have recently wired the downstairs with ethernet cable, and would like to use a wired wireless repeater (bridge) to get a better signal downstairs. What hardware should I use?

    I have a similar but slightly different issue/question. I didn't know whether to start a new post but I will try here first. I'm not able to set up a 5GHz roaming network.
    I am a self employed songwriter and need 5GHz speed for numerous devices that stream video and music (computers, DirecTv, Tivos, AppleTVs etc.). All these have both wireless cards and Ethernet cables connected for backup. I need the 2GHz radio only for iPhones or guests. I have ATT DSL with 5 static IP addresses. The first is assigned to TCdual and "shared". My older "L" shaped home is tuff on wireless signals (plaster walls etc). Since I've had a lot of trouble with WDS and wireless connections, years ago, I ran Ethernet to every network device as backup, including an Ethernet connected Airport Express, with wireless turned off, I dedicated exclusively to Remote Tunes. It's been working the past few months (knock on wood). But I need to extend TCdual's 5GHz network with roaming. Here's what I've tried without success.
    I placed a 2nd Airport with 5GHz (the model before TC dual) in the room TC's 5GHz will not reach and connected it to TC via ethernet. Using Airport Utility, I tried to "extend" TC's 5GHz network. No luck. AU will only extend TC's default network, which is 2GHz. Very frustrating. So... the only way to get 5GHz in this room is to create a 2nd 5GHz network on Airport #2. Even using the same network name does not create roaming. Whenever I move MBP from this room, I lose Airport#2's 5GHz network and every WAN/LAN connection. I have to reconnect to TC's 5GHz network, every other WAN/LAN device, resume downloads, iChats etc. and start again. VERY frustrating. I think I must be missing something. Am I really forced to choose between speed or roaming. Can't I set up a 5GHz roaming network and have both?

  • Wireless Network with Time Capsule -- 2 Questions (5 GHz? 2nd Network?)

    Hi all:
    First off, thanks to all of you for being there. Apple Discussion Boards are the best!
    OK, to start with, here's my gear list:
    -iMac 27" QC (bought Dec. '09), 2.8 GHz, 8 GB RAM, running 10.6.4
    -Time Capsule 802.11n, 1 TB (bought April '10)
    -Airport Express 802.11n (bought April '10)
    -iPad
    -iPhone 4
    So I set up the Time Capsule a few months ago, and paired it with my iMac and with the Airport Express (to stream AirTunes), and everything has been working fine.
    The iPad and iPhone are also working fine. (In Airport Utility > Advanced > Logs, the iPhone shows a rate of 72, signal -60, and noise -94. And the iMac shows a rate of 300, signal -47, and noise -96. Don't know if that is good or bad or normal.)
    So, here are my questions:
    First, in Airport Utility > AirPort > Wireless > Wireless Network Options... should I check the box that says "5 GHz Network Name"? It is currently not checked. Would that increase performance? (All my devices - iPad, iPhone, Airport Express - are "n" devices, right? Does that mean I should check that box? Is that even an issue?)
    Second, when I first set up my wireless network I named it "MP Network." But I notice in System Preferences > Airport > Advanced that there is another network that apparently was set up when I first set up the TC. Its name is "Apple Network" plus 3 letters and 3 numbers.
    What is that? It doesn't show up anywhere else. Should I delete it? Is it using up bandwidth by being there?
    (Both networks appear in that same place on System Preferences, and both are WPA2 Personal.)
    Thanks to anyone for any input/advice. And apologies if any of the above is confusing.
    Matt

    +So it sounds like I should leave the network as is, right?+
    Yes, this makes sense for most users. Some users sometimes have trouble with a new computer that sometimes connects to the 5 GHz network and sometimes connects to the 2.4 GHz network. They want the computer to always connect to the 5 GHz network so they assign a separate name to that network and configure their computer to connect to that network first.
    +The iPhone being "g" does not reduce my overall performance, right?+
    No, because it's using the 2.4 GHz band. Faster devices use the 5 GHz band.
    +And my TC broadcasts dual band so the "n" devices get what they want and the "g" device gets what it wants...correct?+
    Yes, but you need to remember that "n" devices can connect at either 2.4 GHz or 5 GHz.
    +(The 300 Mbits/sec I am getting on my iMac is good, right? And is 72 for the iPhone good, too?)+
    300 Mbps is outstanding. Most users average 220-270 with a good connection. The iPhone is a "g" device, which means it can operate up to 54 Mbps, so I'm not sure what you are seeing here.
    +As for the other issue of the "out of the box" network name, I think I will delete it. (I am of the school that enjoys things clean and avoids unnecessary clutter!) But will that create any problems for me? Is it as simple as clicking the "-" (remove) icon in System Preferences > Network > AirPort tab?+
    That's all you have to do.
    I can't remember if the password for the Apple Network xxxxxxx is stored in Keychain Access.
    Macintosh HD > Applications > Utilities > KeyChain Access
    Look for a listing of the Apple Network xxxxxx and delete that entry if you want to remove all evidence of that network.

  • Can I use apple TV on home network with time capsule or Airport Xtreme without being connected to the internet?

    I'm wondering if I can use Apple TV to play movies and slide shows on my TV, play music over my sound system and print from my devices (Iphone 4S, iPad and MacBook pro 2011) by using an Airport Xtreme or Time Capsule (to back up the devices) if those devices are not connected to the internet. Can anyone advise pls? Reason for this is that I work on a moving ship and don't have an internet connection to speak of for much of the time (and if I do it's a wireless system that I need to pay by the minute and that is too slow to support the Apple TV), but would all the same like to create a wireless environment where my devices can interact with each other. I seem to get conficting info and a rep at the apple store in Honolulu told me that you cannot use Airport Xtreme or Time Capsule without an internet connection (it was busy, he may have misunderstood my question).
    Looking forward to your input.

    Don't try to home share it.. as that is dependent on using Apple ID.
    Just airplay to the ATV.. iTunes: Using AirPlay
    The movie should play exactly as your doing music.. but get rid of the whole home share if that is causing issues.. there is no mention of needing home share in the above..
    If you still have issues you might need to do it other ways.. like export the movie from itunes.. and play it using vlc which should allow you to stream it to the apple TV using airplay.
    That is a bit tricky and I have not used that setup but it should work.
    http://apple.stackexchange.com/questions/23412/can-i-stream-any-video-played-wit h-vlc-player-to-apple-tv
    If you have a hunt around you should find it fairly easy to do.. but straight airplay should work.. there is a very recent update to ATV which might help it with airplay.
