Extreme in WPA2 and Bridge mode

Extreme (802.11n) that we want to use as Access Point. Latest firmware v7.4.1.
Setting the Extreme up with no wireless security let me connect users wirelessly with the Extreme in Bridge mode. Using WPA/WPA2 only works when the Extreme is not in Bridge mode. Using Bridge mode and WPA/WPA2 causes complete loss to the unit, even with Airport Utility.
Thanks

The Verizon modem/router is already providing DHCP and NAT services for the network.
If you have the AirPort Extreme that is connected to the Verizon modem/router also setup to provide DHCP and NAT, as you state, then you have two devices both trying to provide routing services for the network.
You only want one device providing DHCP and NAT for a network.
You are likely not getting DHCP IP address conflicts since Apple uses a different DHCP range than Verizon, but with both devices providing NAT services, it is easy to see why you are picking up the Double NAT error.
All of your Apple devices need to be in Bridge Mode if you want to avoid the Double NAT error.

How do I configure my Airport Extreme to work in Bridge Mode and provide specific IP addresses to clients

My Airport Extreme is working with an Airport Express to wirelessly extend my wireless network. Both Airports are configured in Bridge Mode per the instructions I found on Apple's support site. I want to assign a specific DHCP address to a wireless camera that is in range of the Extreme, but I understand that the Extreme needs to be in DHCP Only mode to do this. But if I change the mode to DHCP Only, the Extreme will lose contact with the Express. How can I get both functions to work - wireless network extension and specific DHCP addresses?

Then what device is providing DHCP? Only once device per subnet should be the DHCP server. One should be DHCP and NAT and the other in Bridge mode for most home setups. The unit with DHCP and NAT should be the one connected to your cable or DSL and the other set in Bridge mode only extends your network.
On the wireless config page set whichever you're using to extend your network to "Extend a wireless network" and give it the details of the network to which you're attaching it.

Airport Extreme ethernet routing in Bridge Mode

i had(!) the following scenario Airport Extreme (5th Generation) .. via WAN connect to the modem, Ethernet to serval switches, WiFi acting as WDS Main
the WDS Slaves are 3 small Airport express and one Airport Extreme (1st Generation)
due a cabeling problem i had to move the WAN Modem .. and connected it to the 1st generation airport extreme created a Joined network (not WDS) enabled DHCP on the same device.
the new Airport extreme (5th generation) and the Airport Express joined the same network and running in bridge mode.
everything works just like before .. all networks parts can connect to each other, anywhere else including the internet.
exept of anything connected to the ethernet ports of the (now slaved) airport extreme (5th generation) anything connected there seems not to be routed at all ..
they have a physical connection (link show on the Airport and on the Switch. but there is zero data going trough ... no DHCP adresses assigned. manually assign a IP in the same network results in the same effect (can't even ping the directly connected Airport Extreme.
is this a Bug ?

oh ic ... thats why it worked before the other way arround ...
well does still not make any sense to me .. but you are 100% right ..
enabeling WDS on the Airport Extreme (1gen) and doing slave the Airport extreme (5 gen) works fine .. but the connection times are about 10 times slower than in a joined network.
which makes the whole show extremly slow ...
it takes some times 5 minutes and a million time clicking (assign new) to just get an IP adress ... even if the dhcp running on the same Airport where the client is connecting to ..
if the 5gen APE is WDS master .. and the 1gen is WDS Slave (my old setup) .. this problem is not existing ...
but then ican't connect the WAN modem to the slaved Airport since the slave is always bridged and the master requires internet connectivity trough the local Wan port
any idea to get arround this ?

AT&T UVerse, Time Capsule, and Bridge Mode

I know that this topic has been touched on, but I've yet to find a solution to the problem I'm having with my Time Capsule. I am an AT&T Uverse subscriber which means I have their big residential gateway (RG) modem/router/VoIP/TV box in my house. I also have a 1st gen Time Capsule (TC) and an 8-port gigabit switch to feed ethernet to the wall jacks throughout my house.
What I'm trying to setup is to have the RG provide 802.11g, the TC provide 802.11n, for the TC to feed the gigabit switch to bring 1GB ethernet to all of my wall jacks, and for everything on g, n, and ethernet to be able to see each other. I originally was using the TC alone with DMZ+, but now that I actually have some wireless-n devices, I'd really like to separate the two networks (I have a wireless-g printer and a macbook that will slow it all down).
I tried putting the TC in Bridge mode, made an n-network and a g-network, and turned off DMZ+. The result was that RG connected devices could see into the TC connected devices and had Internet access, TC connected devices could not see out past the TC or get Internet access, except Bonjour devices were able to see each other (I have a wired Mac Mini on the TC, which could see the MacBook even when connected to the RG by wireless-g).
Basically, I'm trying to set up the RG as my router with 802.11g, and have the TC as a switch providing GB ethernet and 802.11n. Is this possible?
If I had the 2nd gen TC then none of this would be necessary since it has the dual radios, but I'm trying to make due with what I"ve got!
Thanks in advance for any help.

As I understand home routers/switches, even though the RG is only 100Mb ethernet, devices on the Gb switch will communicate with each other at GB speeds as managed by the switch.
You are correct. I interpreted your statement to mean that you wanted Gigabit throughout the network. Devices connected to the TC would indeed have the benefit of Gigabit available.
I have another idea. You are configuring what is known as a "roaming" wireless network. The requirements here are that the TC be in "bridge mode" (It is) and that you use the exact same wireless network name (you probably are), security and password.
Can you check the wireless security settings on the Uverse router? ATT may use different terminology. For example, you might have WPA2 Personal selected as security on the TC, but maybe something like WPA-PSK (TKIP) on the Uverse. If the security settings on both routers do not match exactly, you really have two distinct networks and they will not function as one.
That might explain why you see some devices from one router and but not the other. What security settings do you have on both routers?

X3500 "RFC 2684 Bridged" and "Bridged mode only" at the same time

Is it possible to achive this? With some older modem i could configure one ethernet port for Bridged mode only, so that i could connect directly to Internet through that port with own ip given by my ISP, and at the same time have the modem handle NAT internet connection for WLAN and other ethernet ports.
I really need this feature, is it possible with Linksys X3500?

Hi, the router does not have that feature. You can only select one internet connection type at a time. You may need to check on business class modem/router; perhaps they do have that feature.

Specific differences between AP and bridge modes?

I've RTFM'd everywhere but cannot find anything definitive regarding the differences between AP+client versus bridge+bridge modes.
Presume you have a pair of AP1200's. First test case: One is in AP mode and the other is in WGB mode. Second test case: One is in root-bridge mode and the other is in non-root-bridge mode.
In both cases traffic will pass bidirectionally from one Ethernet port to the other. What, then, are the technical differences between these two situations? Do the "bridges" place less load on the AP1200's CPU? Does AP-based operation yield more diagnostic data? What are the advantages and disadvantages of each mode?
I can't find anything that digs into the details. Any help appreciated. Thanks!

Thanks for your response. A few comments, and then a question:
* Looks to the AP just like a standard client, so it interoperates with all APs
What does? A 1200 in WGB mode? If so, then yes it looks like a standard client to the AP but Cisco explicitly states it will only associate with other Cisco AP's. It is not compatible with "all APs".
If you mean a non-root-bridge looks like a standard client to an AP, that's true but the AP must be in "AP with wireless clients" mode which is not one of the test cases I was asking about.
* No configuration required
Of the WGB? Mine need configuration: SSID, encryption keys, etc. It's just like setting it up as an AP except for the mode you select.
Of a (non-)root-bridge? Mine have needed configuration in that mode, too. Same as above.
Not sure what you mean by "no configuration required".
# Disadvantages:
* Supports only a single wired client
Nope, in WGB mode pre-1200 units supported up to eight wired devices. 1200's and later support up to 250 clients. Cisco docs are clear on this.
In bridge mode I'm not aware of any wired client limits. The device is simply passing traffic between the two interfaces.
* WGB itself is not manageable
Not sure what you mean by "not managable".
Back to my question: What is the difference between AP+client mode vs. root-bridge+non-root-bridge mode? Does the AP+client mode make more decisions about traffic routing or prioritization, while bridge-based operation is less "intelligent"? Something else?
My tests show no discernable difference in throughput, even with multiple clients/nonroot bridges. When multiple users consume bandwidth simultaneously, it is shared among them just as you'd expect.
So... what ARE the differences, as far as the decisions IOS is making, between the different modes?
Thanks!

CSM route mode and bridge mode can exist at the same time?

I'm using CSM on ver 4.x,and I used to the bridge mode for firewall load balance,for a new requset,I have to create a new server/client vlan,but the original firewall load balance was effected when I issued the server vlan command,and I'd like to use route mode for the new server farm,I'm wondering that route mode and brige mode can't exist at the same time,because it seems it doesn't make sense.Any reply will be very appreciated.

you can use bridge mode and route mode at the same time.
Traffic with desintation mac address being the CSM will be routed, otherwise it will be bridged.

Guest network and bridge mode

Hi,
my question is, why my guest network doesn't works, if my TimeCapsule works in the bridge mode?
Someone an idea?
Thanks
Albrun

From the latest airport utility and firmware it does work.
I run the TC in bridge and setup the guest to try it.. seems to work for me.
I know there are other issues with using these .. perhaps that is what you mean.. but it does work.

OpenVPN and bridge mode tunnels - Wiki'fied.

After spending the last couple of days messing around with OpenVPN to work in bridge mode, I've made a wiki to help other people.
I assigned a couple of variables in /etc/rc.conf - I hope that's not against the Arch way of doing stuff. And I could use some help on my /etc/rc.d/openvpn to make it more elegant (see my note in the wiki)
Let me know if it works or doesn't work for anyone else.

Flexconnect and Bridge Mode on same AP with WLC

Hello.
I want to use Flexconnect togheter with Mesh AP's. But if i choose Bridge Mode the option Flexconnect dissapears after the AP have restartet.
I 'm using Flexconnect because we want to us the local breakout to the internet. We dont want to reroute the whole trafiic from the branch office to the WLC.
That should be possible ? Regards Patrick

Two different things... if you want to extend the wireless without any Ethernet cables, then you need to do mesh... this means you need to have a RAP and your MAP (no Ethernet required). The MAP will associate to only a RAP and then you can extend the wireless. YOu might want to look at WGB, but these are autonomous and you need to follow these examples:

Using an airport extreme in both bridged mode and guest network with DHCP

I currently use a third-generation airport extreme in bridge mode to connect my various Mac servers To the Internet. I'm using bridge mode on the AirPort Extreme because I have up to five static IP address (only using three now) I am currently not using the wireless network, and none of the servers are serving DHCP. I am looking at the Newer airport extreme with guest network Wi-Fi. My question is, does the new airport extreme base station support bridge- mode for any devices and host DHCP for the guest network connecting wirelessly to the base station?

The AirPort Extreme cannot be in Bridge Mode and support a Guest Network.
The AirPort must be configured to provide DHCP and NAT services if you want to enable the Guest Network function.
If you really do have a 3rd Gen AirPort Extreme, it will support the Guest Network feature if you connect the AirPort directly to a simple modem.....not a modem/router or gateway type of devices.......and configure the AirPort to provide DHCP and NAT services for the network.

Adding 3 Airport Extremes to Linksys WGT4400N in Bridge Mode Not working

I have a network that starts in a homerun closet and is expanded across 5 acres to differnet locations via CAT5e.
Homerun Closet has Linksys WGT4400N with Cat5e running to three different locations on property. The cables are within length limitations.
1st Airport Extreme N Running in Bridge Mode Connected and Working in Main House
2nd Airport Extreme N Running in Bridge Mode Connected and Working in Guest House
3rd Airport Extreme Replaced with new one Connected and Not Working in Office. This Airport Extreme N is configured just like the others but it cannot see the network. Cables Verified with Testers and Mac Pro at office location, works when ethernet cable is directly connected to system.
Not sure what is going on. IS there s limit to the number of Airport Extreme N's used as bridges?
I have 2 of ther working and the last is not. First Airport Extreme N for office was bad replaced.
Thank You

The Netgear wireless server has control over what what devices are allowed to connect.
Unless you tell the Netgear what devices you want to allow to connect, it will allow any wireless device to connect as long as it knows the wireless network password.
IF.... .you were using two AirPort Extremes, and not a Netgear, the two Extremes would communicate to each other....so you would only have to enter Timed Access settings on one router and other AirPort would automatically pick those settings up.
But, even this was not the case until the last year or so when Apple updated firmware. A few years ago, you might have had 2 Apple AirPort Extremes on the network, but you still had to manually set up Timed Access on both devices separately.
Bottom line, you need to setup the equivalent of Timed Access on the Netgear router.

Airport Extreme Bridge Mode Connection Drop

Hi everyone,
Hoping that someone will be able to help me. I have a one year old son who is now getting his hands into everything so a few weeks ago I decided to look at my options for networking my home iMac and External HD's.
I am currently running a SKY (Netgear router) into an Airport Extreme set up in Bridge mode. I have turned off the SSID of the SKY Router and everything connects to the Airport. On the AIrport I have a USB hub attached which then has three external HDs attached to it. I know this is a lot, but I have not had any issues at all with data transfer with this set up.
The issues I am having is that on average, once or twice a day the iMac will drop connection to the Airport. There is no patern to this as the iMac will drop connection while I have been working on the machine and also at times when it has been woken from sleep mode. There is then no physical way to restore the connection unless I restart the iMac. Even turning on/off airport does not fix the issue. If I try this, the iMac then seems to not be able to find any wirless networks, even those that are in the area of my home.
I have turn off the the airport and ran the iMac simply connecting to the SKY router and have experienced zero problems, the issue only happens when I introduce the Airport Extreme.
Does anyone know what might be causing the problem? I really need to try to get this to work so that I can eliminate the need to have the external hard drives attached physically to the iMac. In my home the router/Airport and drives are safely out of the way in a child proof area. I fear that if I have to introduce them back to being physically connected to the iMac they will no longer be safe from small hands!!!
Many thanks for any advice.
- Neil

Unfortunately, you did not not include information about the operating system that you will use to configure the AirPort Extreme, so we would need that you be able to provide you with the correct steps to set up the AirPort Extreme.
Bridge Mode would be the correct setting for the AirPort Extreme, but you will not have to worry about this if you use the setup "wizard" in AirPort Utility on your Mac or an iPhone / iPad since the wizard will automatically provide the correct settings for the AirPort Extreme.
I'm not clear though on whether you want the AirPort Extreme to provide another separate wireless network or extend the existing Arris network. If you plan to locate the AirPort Extreme a room or two away from the Arris, then it might make sense to extend the Arris network, so you will have one "big" network that provides greater range.
Whether or not the Arris will have NAT issues, we cannot say. This will be one of those times where you will not know whether something will work correctly until you try.
If you are not in a rush to get the AirPort Extreme configured, temporarily power off the Extreme and get things working with the Arris modem/router and your Xbox.

HT4259 Cant extend airport extreme in bridge mode?

My configuration is: Internet Cable Modem --> Airport Extreme (bridge mode) --> Airport Express (extend)
My primary wi-fi base station (airport extreme) is set to bridge mode because the cable modem has the DHCP enable. Is it possible to extend it wirelessly with an airport express in other room of the house?
Thanks!

What is the approximate distance from the AirPort Exteme to the location of the AirPort Express?
12 meters (another room)
Distance here in and of itself should not be a problem.
How many obstructions are there in the signal path between the AirPort Extreme and the AirPort Express?
3 walls, 1 cordless phone
A single wall can absorb anywhere from 10-20% of the signal or more depending on the type of construction. If the wallboard/insulation type has foil backing...as many walls do...even more of the signal is likely being absorbed.
At best, the AirPort Express is picking up a signal that is likely 30-35% degraded. At worst, it is getting a signal that has degraded 70-80%, possibly more. As I said, the Express can only repeat the quality of signal that it receives.
The effect of the cordless phone is unknown, but I would note that cordless phones are the main culprits that interfere with wireless network signals in a home.
How many obstructions are there in the signal path between the AirPort Express and the general remote area where more signal coverage is needed?
No obstructions (same room).
Thanks for that info.
I would suggest that you move the AirPort Express closer to the AirPort Extreme. by 5-10 meters. You may need to experiment with several locations to see if the performance improves in the remote area where you need more wireless signal coverage.
Anything that you can do to eliminate or minimize obstructions in the wireless signal path will help. As an example, I cannot get an acceptable signal in my home in any area where the signal must pass through more than 2 walls.
If you do not notice any significant improvement, your home is simply not going to work with a wireless signal extension setup....and you will need to consider connecting the AirPort Extreme and AirPort Express together using a permanent wired Ethernet connection. As you might imagine, there is no signal loss in a wire, so this type of setup will work much better than what you are trying to do.
If I put the extreme and express side by side wirelessly (same room) is there a way to know if I am connected to the main or to the repeater?
You will need a Mac laptop to check. There is no need to locate the AirPort devices side by side...they can be located where they are now.
Locate your Mac laptop very close to the AirPort Extreme
Hold down the option key on the Mac while you click on the AirPort icon at the top of the screen
Look for the BSSID and jot that down
The BSSID is the specific ID of the AirPort device to which you are connected.
Now move the laptop very close to the AirPort Express
Perform the same test
If your Mac is connecting to the Express, you will see a different BSSID
If you see the same BSSID as the AirPort Extreme, the laptop is still connecting to the AirPort Extreme....and the Express is not extending the signal at all.

Can i connect hard drive to airport extreme in bridge mode

I just bought a hard drive and want have it connected to my airport extreme which is in bridge mode so that I can use it with U verse. Will I be able to backup my files on my macbook without connecting the usb on the hard drive to the macbook itself?

Will I be able to backup my files on my macbook without connecting the usb on the hard drive to the macbook itself?
This all depends on what you mean by backup your files.
Apple does not support Time Machine backups to a drive at the USB port of the AirPort Extreme, so if you are planning to use Time Machine, the better strategy would be to connect the drive directly to your Mac.
If you want to drag/drop or copy/paste regular data files to the hard drive, that should work OK
Remember that the drive should be formatted in Mac OS Extended (Journaled) as most store bought drives will come pre-formatted for Windows NTFS.
The USB port at the AirPort Extreme is under powered, so you almost always have to use a powered USB hub with a hard drive here....even if the drive has its own power supply.
