Bridging wireless and wired network interfaces

Hi,
Is it possible to "bridge" the airport and ethernet network interfaces on a macbook pro using Leopard (10.5.7) ? I do not mean Internet connection sharing. That results in NAT.
I recently got a desktop in my room which doesn't have a WiFi interface. I wish to connect its wired interfaced to my mbp's wired interface and give it access to the wireless network my mbp is on. To do this I would need to bridge the wireless and wired interfaces on my mbp. All the results I find online to do this only talk about Internet Connection Sharing ..
thanks,
regards,
Puneet

You can turn on IP Forwarding to achieve most of what you're after:
sudo sysctl -w net.inet.ip.forwarding=1
This will have the Mac forward packets from one interface to the other without NAT.
However you still need to use separate subnets, and may need to play with routing to get everyone to talk to each other.

ACS 5.4 with DACL over wireless and wired network

Hi my name is Ivan, I have a question
I have a deployment in my network wired at this way:
Profile 1: corporate's users are working with 802.1X to authenticate computers and users with eap peap mschap v2 and Mac Filtering configuring in the Cisco WLC. My ACS 5.4 is integrate to the Active Directory.
Profile 2: Telephonies IP authenticate with MAB. All the Mac Address are registered in to the ACS locally.
Profile 3: user guest authenticate with portal web from Cisco Wireless Lan Controller over the wired network, and the account exist in to the WLC Lobby Ambassador
A my deployment in the wireless network is in this way:
Flex Connect with central authentication and local switching to connect 15 sites over the wan network.
SSID 1: users corporate working with 802.1X to authenticate users with peap mschap v2 and Mac Filtering configuring in the Cisco WLC. My ACS 5.4 is integrate to Active Directory.
SSID 2: users guest working with portal web from Cisco Wireless Lan Controller over the wireless network, and the account exist in to the WLC Lobby Ambassador.
I would like to configure in the Cisco ACS 5.4 Downloadable Access List (DACL) to use in my network wired and wireless.
How can I do it to my scenary?
Please could you help me?
Regards
Ivan.

Hello. To avoid confusion, let's divide the WLC based upon the operating system.
There are WLCs who run AirOS. That includes WLC 4400, but also includes WLC 5500.
There are WLCs who run IOS-XE. That includes the new Catalyst 3850-X and WLC 5700. (also I think can run AirOS too).
IOS-XE fully support DACL. On the other hand AirOS support DACL partially.
From ACS point of view, when you configure DACL for IOS you configure not only the name of the access-list, but also the access-list entries. That way the IOS devices don't need to have the ACLs pre-configured. This is great because you only need to create and update the access-list entries from only one place (which is ACS) and deploy easily to hundreds of switches.
On the other hand, when ACS configures DACL for AirOS it can only specify the name of the access-list. The AirOS device needs to configure the access-list with a name exactly as configured on the ACS. Sadly, each AirOS device also needs to configure all acess-list entries.
It seems you want to configure DACL along with other attributes. If you explain me a little more your requirement I can show you what to configure.
Best regards

Wireless and Wired Network/Bonjour Printer Settings.

I am setting up a network for a preschool that has six Macs (MacBook, iMac Intel, Mac Mini Intel, eMac G4, iMac G5) on a network spread out around the school. Some teachers bring in their own laptops, but no frequently and most are Macs.
The network is currently arranged like this:
Office:
Bellsouth DSL Router with one RJ-45 ethernet wire running to the WAN port on an Apple AirPort Extreme (802.11g).
One RJ-45 ethernet wire runs from the Apple AirPort Extreme (802.11g) LAN port out of the office to a network switch in the Library.
All three Macs in the Office are currently connected wirelessly with Airport cards.
Library/Lounge:
One network switch with an RJ-45 ethernet wire from the Office running into it and two RJ-45 ethernet wires running out of it to:
One eMac connected via ethernet from the switch in the library.
One iMac G5 connected via ethernet from the switch to the Teacher's Lounge.
I am currently sharing one laser printer via Bonjour that is plugged directly into the Apple AirPort Extreme (802.11g) via USB in the office.
There is currently one inkjet in the Teacher's Lounge plugged directly into the iMac G5 and is being shared from that iMac.
Here is my question:
I would like to hardwire the iMac Intel and Mac Mini (office Macs) directly to the network to improve file transfer speed between the Accountant's Mini and the Office Manager's iMac Intel. I have two options, I could run a wire to a network switch from the Lan port from the Apple AirPort Extreme (802.11g) and then connect the two Office Macs and the two Library/Lounge Macs directly from there and I assume that all thusly connected Macs would have Bonjour access to the laser printer. However, I noticed a setting in the (round topped) Airport Extreme's setup utility that said something about "do you want to connect to Bonjour with a wired (whatever" I can't remember the wording exactly, but does a setting like this one need to be checked to share that printer both across the wireless network AND the wired computers as well?
I want to be able to share the laser across the network and the inkjet that is being shared from the G5 across the network and a future Office inkjet that, I assume, I will have to plug into one of the Office Macs to share. I can't put a USB hub on the AAEX to share via Bonjour, so my options seem to be limited. Any suggestions or workarounds for doing this better?
Do the new "N" Airports allow printers to be daisy-chained on a USB hub and shared via Bonjour?
BTW, I prefer Bonjour from the AAEX because the printer's available even when all other Macs are off or sleeping.

Wireless and wired network set up?

Currently I have one iMac and two PCs connecting wirelessly to my Airport Extreme. One of the PCs found it without any issues...the other PC crashed and had to be rebuilt during the 3 days of trouble shooting. When it was rebuilt it to found the Airport without an issue. Never did figure out the issue and feel pretty lucky. Now here is my question...I have an older Gateway Desktop that was hard wired into the Airport, but it is in another room now and I want to connect it to the network for one of my younger children. It is nowhere near my base station or other computers or a cable outlet for DSL access. It also has no Wireless card...yes it is that old. Is there a way to use the Airport Express to wirelessly capture my signal, but then hard wire into the Ethernet port? If not this...than any other suggestions would be helpful. Thanks!

I would suggest a USB wireless network adaptor. It will probably cost around 20$.

Wireless and wired network??

I'm not terribly computer savvy. I have a few PC's here and a brand new iMac. My current network is wired and what I want to do is put in a new network that will work with both pc and my iMac and will be wired for the PC's and wireless for the iMac.
What do I buy, whats the best, fastest and very important, the easiest?

Hi susan-kelly
I have been a fan of AirPort Base Stations for quite some time. They are quite easy to set up.
This link may be helpful as far as the basics go: Creating a small Ethernet network
This link is more specific to getting the PC's and Macs to actually talk to one another and is a little more technical: Networking with a Windows PC

Connecting two WRV200's to share same wireless and wired network

I am looking at purchasing a second WRV200. I want to have both wired together on the same network along with having them include the wireless on both to the same network. i.e. having two wired locations and two wireless AP's to get on to the one network.
Is there a way to configure two WRV200's to do this?
Regards...

Yes. You can use the access point inside the WRV200 bypassing all the router functions. You configure the second WRV with a free LAN IP address inside your main LAN (e.g. 192.168.1.2 if 192.168.1.1 is your main router). You disable the DHCP server on the second WRV. Then you wire a numbered LAN port of the second WRV to your existing LAN. Do not use the internet port of the second WRV. Now you only use the wireless access point and the switch inside the WRV.
To create a single wireless roaming network you set up the wireless on both WRVs with identical wireless settings (SSID, wireless security, keys, etc.) The only difference should be in the allocation of channels. They should not use the same channel to avoid interference.

Connecting to wireless AND wired network at the same time.

I just bought 2 lacie 500 GB Network Hard Drives with Gigabit Ethernet. One for file storage, the other for a backup of the first drive.
My iMac connects to my DSL router using a Linksys wireless G Access Point, which is in another room in my apartment, due to the genius contractor installing only one telephone jack.
So can I use my iMac's ethernet port to connect to a gigabit switch, and then connect the 2 external HDD to the switch? I don't need the other computers on my network to have access to the external HHD, just my iMac. However I do need to be on the 'net and have access to the external HDDs at the same time.
Thanks

No problem at all, the Interface that connects to the Internet, needs to be drug to the top of Network>Show:>Network Port Configurations and checked ON.
So drag Airport to the top, Ethernet second and you should be good to go.

WiFi Network and Wired Network

In your opinion, what would be the best configuration of a combination WiFi and wired network. Here's the situation. In my apartment, my living room is very close to my office, WiFi converage is good from the LR to the office where I have my servers and internet connection etc. But in order to provide stellar performance, I wanted to add an Access Point or Airport Express in the LR to make the signal that much better.
In this situation, would you have the Internet Modem, Time Capsule, in the office and the Airport Express in the LR? I'm assuming that would provide the best wireless coverage for the entire apartment. My only concern is the speed accessing the Time Capsule as well as the 1TB NAS as well as SAN File Storage connected to the core switch I have in my office, which is a Cisco 3750G (10/100/1000) over WiFi. I think this would be the best solution. Thanks.

But how is the AP linked back to the office.. if you are wireless repeating.. then you lose whatever you gain.. and probably worse than lose.. you introduce double hop wireless.. This is only going to work if you have ethernet link.. and then Express should be replaced by Extreme.. as Express still uses 10/100 port. Decent wireless should saturate that. (Seldom does.. but if you are doing calcuations I am sure you can see the problem).
Do you get decent 5ghz in the LR?? The key to fast wireless is using 5ghz especially in apartment complex where you are probably surrounded by 2.4ghz wireless.
If the current equipment does not allow you decent 5ghz connection.. strongly suggest you run a single ethernet between the office and the LR and use that.. with Extreme or better AP..
If you want to start wireless bridging at 5ghz.. look at ubiquiti stuff.. it is head and shoulders above domestic standard equipment for not too big a premium.

The best way to connect wireless and wired for a WRT160N.

It took me about 4 hours to find out how to connect wireless and wired to a network using model WRT160N. Here is what I have done. First install the CD when it says there is not connection connect your PC, Modem and router Andy any wireless are wired products, after that do what the linksys advisor tells your which is default. When it gives you the security key write it down because you will need it for your wireless and wired Products. Under security mode type your SDD name and where key 1 is type your security password with was given to you. Remember all you wireless products have to have the same SDD Like Linsys and all your wired products have to have a different name like Linsys2 but your Key 1 numbers has to stay the same. That is all you have to do. Remember that wireless and wired has to be in sequence. That should do it.

Hi David Hamilton1;
I guess that all depends on how critical your data is in relation to how much time you want to spend doing the erasure. Those higher level erasure options can take a significant amount of time to complete. Personally I don't have anything on my Mac that I think is worth more time then a simple erasure even if that does leave it some what recoverable. To me it seems some people are going overboard on this issue.

Base Station and wired network

I am looking to replace my current router and am considering an Airport Extreme base station. Hoping to get some questions answered...
I currently have several Macs sharing a cable modem connection. There is also a printer (Epson R200) attached through a print server breakout box. All connected computers are able to share the printer, using the GIMP drivers.
My set up is:
Cable Modem->10/100 router->10/100/1000 switch
The printer and some slower machines are attached to the ports on the router. The faster machines (with Gigabit) are attached to the switch. All connected machines are able to access each other, the net and the shared printer.
The Airport Base Station would replace the router. Ideally, I would like to eliminate the print server box and plug the printer into the print server port on the Base Station.
- Would all machines (wireless and wired) have access to the printer?
- Would it make sense to have some gigabit machines connect via Airport Extreme vs. wired? I realize that the net connection speed would not suffer, but would there be that much of a speed penalty within the network? (gigabit machine to gigabit machine).
- What are the advantage of the Airport Base station over the many other 802.11 b/g routers available?
Thanks,
--Joe

- Would all machines (wireless and wired) have access to the printer?
Yes. All network computer, both wired and wireless will have access to the printer if a suitable driver exists. I don't know about your Epson printer, but some printers have issues. My Canon i850 printer doesn't work well with Tiger when connected to the Airport, but my HP laserjet works perfect.
- Would it make sense to have some gigabit machines connect via Airport Extreme vs. wired?
There is some speed loss but its still really fast. I get a 3.5-3.7 MBits/sec when copying a file from a wired computer to a wireless airport extreme connected computer. Its fast enough unless you copy GB of data.
- What are the advantage of the Airport Base station over the many other 802.11 b/g routers available?
To me its the integration of the Airport with the Mac OS; easily configurable (try to get WPA protection on another station...); more secure because it can be setup to accept only Macs; printer sharing works great and it is simply beautiful. On the downside, the price.

Using a WRT54G as a second wireless and wired router on a LAN

I have setup a WRT54G as a second wired and wireless router on my local LAN.
The WAN wired side of the WRT54G is setup completely DHCP. It gets IP 192.168.1.104 most of the time. (I have used a PC with DHCP on theis ethernet wire and it gets to the internet OK).
The LAN side of the WRT54G is setup as 192.168.20.1 and all wireless and wired devices connecting to it get ips of 192.168.20.xxx and communicate between them selfs perfectly. However, none of them can get to the internet through the WRT54G. What have I done wrong?
Thank You

I guess your WRT54G is not connected to Internet directly, but it's connected to another router that has Internet access.
If this is the case, you can configure this device as access point/hub only in order to get Internet access from the other router. Ignore the WAN connection on this WRT54G, just connect both router's LAN port with crossover cable.. After that configure the WRT54G's wireless setting. You can get more detailed info on how to do it in following article:
Quick Guide to Configure Wireless Router as Access Point
Hope helps..

Can an airport express support wireless and wired connection at the same time

im wondering if i can use wireless and wired connection at the same time

The Ethernet port that the old AirPort Express has got is to connect the AirPort Express to your modem, not to connect another PC or Mac, so you can only connect wireless devices to the AirPort Express.
If you have the new AirPort Express, you can connect a wired PC or Mac and more wireless devices or computers at the same tiem

HP LaserJet P1505n stops printing and blocks network interface

I have been using my P1505n for over two years without any problem. But it suddenly stopped printing. The scenario is as follows:
1. The P1505n is connected to a wired home network with reserved IP address in the DHCP server.
2. The P1505n is used from Ubuntu 10.4, 11.4 , Windows XP and Windows 7 without any previous problems.
3. The last partial successful print job stopped in the middle of a page leaving the rest blank: no paper jam.
4. I have reset the printer several times: turn off + press Cancel & Go + turn on while holding the two buttons down.
5. The first reset was successful: the toner level going from 40 to 100%. The next ones may have been successfull too.
6. After each reset and also after each power-on, I can ping and access the embedded web server.
7. Whenever I send a print job, the print queue on the computer (all OS behave identically) says "printing" and stops. I can cancel/remove the jobs from Ubuntu.
8. After the printer receives the print job, it silently blocks the network interface (no ping nor web) and doesn't print anything. No movementsm no LED blinking either: just nothing happens.
What is the reason for this problem? And how do I solve it?

Hi firedude007,
Welcome to the HP Forums!
I see that your HP Laserjet P1102w stops printing files from your Mac but not on Windows, and I am happy to help!
For further assistance, I will need to know the following information:
The version number of the Mac Operating System. To find the exact version, visit this link. Whatsmyos.
If the printer is connected, Wireless, or USB.
If the printer is able to make copies by itself.
In the meantime, I would try the following:
Reset the printing system. Mac OS X: How to reset the printing system.
Verify and repair disk permissions. Disk Utility 12.x: Repair disk permissions.
Hope to hear from you, and thank you for posting!
