Guest access in bridge mode

I want to set up a secure wireless network in our small office that will also allow clients to access the internet while in our waiting area. I also want to maintain our current wired network, which is connected to the internet through a Nortel router, connected to a DSL modem. Where would the Airport extreme be installed? - i.e., upstream or downstream from the router? Also, looking over Apple's network documentation, it appears that the Airport Extreme would be in Bridge mode when configured on an existing ethernet network with router, but the documentation is clear on the issue of setting up guest access in this kind of configuration.
In case you have not guessed, I am not an IT guy, so will be grateful for any helpful suggestions

Guest access and bridge mode are incompatible on AirPort base stations. I'd connect an AirPort Extreme to your DSL modem, connect your wired network connections to the Ethernet ports of the AirPort Extreme, and take the Nortel router out of service. Depending on how many wired connections you need, you may also need an Ethernet switch. Besides the WAN port, an AirPort Extreme only has three available Ethernet ports.

  • How can I set up a guest access point with a Time Capsule and an Airport Extreme? I am using a Telus router with the Time Capsule used as a wireless access point (bridge mode). I don't want the guest access point to have access to my network.

    The Guest Network function of the Time Capsule and AirPort Extreme cannot be enabled when the device is in Bridge Mode. Unfortunately, with another router...the Telus...upstream on your network, Bridge Mode is indicated as the correct setting for all other routers on the network.
    If you can replace the Telus gateway with a simple modem (that performs no routing functions), you should be able to configure either the Time Capsule or the AirPort Extreme....whichever is connected to the modem....to provide a Guest Network.

  • AirPort guest wifi in bridge mode v 6

    Oke... seems the configuration is a very limited to what Apple thinks are the basic needs...
    What I really miss is support for Guest network in bridge mode. It ALMOST workst in  6... a shame you can't configure a DHCP server for the Guest network when the main wifi is in bridge mode. You can enable Guest, the client just won't get any IP address... Please fix this! A really usefull function since the AirPort Extreme is used in situation where it isn't the NAT, DHCP or gateway device!
    Also it should be possible to configure the DHCP ranges for main and guest should indepently of each other... and simple disable the DHCP function for one or both. Also client isolation is a nice option.
    Please make it more Office friendly...
    Really make an more advanced view... the aiport is capable of so much more! A pitty it's potential is limited through software configuration issues...
    So make it so in the next generation of the configuration utility! Thank you

    Please tell Apple what you want here.  This support community is comprised of other users, just like you.  Apple is not here.

  • Guest Wireless Access in Bridged Mode e4200v1

    I have an e4200v1 in bridge mode (LAN IP 192.168.1.2) connected via its WAN port to a LAN port on the primary router at 192.168.1.1.
    Guest Wireless works perfectly in Ver. 1.0.04 build 11 but not in Ver. 1.0..05 Build 7.
    ANy ideas?

    I've tried searching the forums for the same concern. I found the following:

  • Guest network in bridged mode (or other non-DHCP mode)

    Hello,
    I have the (Simultaneous Dual Band II) Airport extreme.
    I wanted to use it at work but creating a secure network (my printer, computers, and drives) and a guest network (no password so people can access internet).
    They already have a DHCP server (in the past I have a mistake by forgetting to turn off DHCP on a router which assigned other computers IP address (upstream) which conflicted with their DHCP server and all kinds of problems ensued).
    So I know that in Bridge Mode, the guest network is turned off.
    What are my options? I'm afraid to take if off bridge mode because of the DHCP issue. But I really want to use the dual network mode on the Airport Extreme.
    So I don't want to bring down the whole network, can i safely use something other than bridge mode? other ideas?
    Thanks in advance for any feedback
    (yes I have searched a lot for the issue but I'm not sure what to do)

    First, you question the policies about my work place (none of your business).
    Sorry for suggesting that you check the policies before you violate something that could get you fired.
    But then, you "would bet" that I hooked something wrong (could have asked).
    Sorry but that is certainly a higher probability than a router malfunctioning in that manner.
    It may not be your intention (just as it is not mine to be ungrateful).
    Not sure if you are showing that with your last post.

  • Guest Network in Bridged Mode?

    I'm wondering if you can use the Guest wifi network feature on an Airport Extreme that is in bridged mode. When I say bridged mode, I do NOT mean "extending" a wireless network (like many threads with a smiliar title seem to mean). What I mean is that I have a single Airport Extreme. I want to use it as a wireless access point, while continue to use my ISP's modem/router combo as the DHCP provider. The ISP box will have no wifi enabled. The Airport will connect to that box (via a large switch) and be convfigured as a bridge, instead of "distributing IP addresses" itself.
    I know that in this setup, a regular wireless network is not a problem. But I've never tried a regular and a guest network together, while in bridged mode. I'm hoping this is do-able, because I don't think the DHCP in the ISP box can be turned off. Plus we only planned for a single ethernet cable going up a floor to where this airport is going to live. If it is going to be the DHCP provider too, then there would have to be a second ethernet cable, so the airport can logically be between the ISP box and the switch.

    This is a valuable answer because it clarifies the one piece of the puzzle as to how this might (or might not) work.
    It is obvious that a device connecting to the base station informs the base station as to whether it is on the guest or private network through the SSID it connects to. It's obvious how one can create two overlaid networks through using two different (non-routable) IP address ranges. It's obvious how the base station --- AS DHCP and NAT HOST --- can allocate addresses in these two ranges.
    What was not obvious is how this can all propagate out to a third party DHCP server --- how would that server know to allocate IP addresses in one range rather than the other?
    But use of a VLAN tag answers that question. Very cute use of a (to home users) rather obscure part of the ethernet spec.

  • E4200 as a Access Point/Bridge Mode

    I have spent most of the weekend trying to get this router to act as a proper Access Point.
    Has any got this to work correctly?
    When it does work (Stay connected) speeds and latency are rotten. If I go back to Routing Mode this thing kicks butt, but I isolate all devices attached to a different subnet and trying to set up proper routes has proved imposable.
    Firmware 1.0.2 r 13
    The online help stated to connect to the "internet interface" when in Bridge Mode DHCP Server Is not broadcasting to on the wireless or wired interfaces.
    If I used the wired interface as the uplink I can broadcast the DHCP to any device on wired but again nothing to the Wireless.
    When I "Show Routing Table" I see two static routes pointing to the ATT router for the Wired/Wireless Interfaces.....
    0.0.0.0 255.255.255.0 (my Gateway) Wired/Wireless
    (my Gateway) 255.255.255.0 0.0.0. Wired/Wireless
    Why?? 
    AP mode should only be working in Broadcast.
    By connecting the Wired Interfaces alone up to my switched network should not use the router at all.
    If you force all traffic to my router all traffic has to be inspected by the firewall

    I decided to buy this after reading it offered Bridge/Access Point mode instead of getting the WAP610 because I wanted to have the option to change to routing mode or AP mode.
    Since my ATT Uverse Router Wireless is “g” it takes forever to transfer files to and from my servers.

  • 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.

  • E4200 Bridge Mode + Guest Access?

    Hi,
    I'm trying to set up my E4200 in "Bridge Mode," but want to enable a few things in the wireless settings, such as:
    a) choosing SSIDs and network keys,
    b) enable Guest Access
    I've been able to get things working without too much hassle:
    * factory reset
    * set wireless SSIDs and network keys
    * enable guess access and set password
    * turn on bridge mode
    Everything is basically fine, except that when the device goes into bridge mode it seems that it shuts off *all* web UI. This kind of makes sense, but do I actually understand that correcty? (Or have I simply not found the right connection method?)
    If so, it leads to a couple follow-on questions:
    a) How do I disable Bridge Mode if I want to change any settings? (Is the answer just 'factory reset'?)
    b) Can Guest Access mode work in Bridge Mode?
    So far, I have not been successful in getting the device to display the login page for Guest Access. I'm not sure if that's a config problem with Guest Access or if that just doesn't work in Bridge Mode.
    Any tips/advice appreciated.
    thx

    It's not possible to use guest access in bridge mode. Guest access is only possible when the E4200 operates as router. In bridge mode any wireless network goes directly into the same LAN. Guest separation would not be possible.
    Also don't disable the SSID broadcast.
    http://homecommunity.cisco.com/t5/Wireless-Routers/E4200-Guest-Network-Not-Working/td-p/406345/highl...
    What I'm saying is that it is possible and that I am doing just that on our LAN here at work.
    You pegged me on the linksys devices not allowing higher subnets. Alas, I am used to using DD-WRT and Tomato for years now (where you can use any subnet mask) and took for granted that I have not seen a stock linksys GUI in a long time. However, in bridge mode on the E4200 you are able to set subnet masks as you wish...

  • ML wifi dropping fixed by no double NAT on APE, but no guest network in no NAT bridge mode.

    ML wifi connections drop on Airport Extreme with dual NAT
    I have a 2011 MBP, and a 2010 Airport Extreme.  Ever since installing Mountain Lion, the MBP constantly drops wifi connection to the Airport Extreme.  It doesn't drop wifi connection at the coffee shop. 
    Fixed by bridge mode
    So I started the AirPort Utility.  It informed me the AirPort Extreme (APE) has dual NAT, because the cable modem has NAT, and to change the APE to bridge mode.  I did that.  It fixed it!  No dropped wifi.  However, a few hours later, my neighbors came and told me the guest network is gone!  So it fixed it for me, but broke my neighbor's connection.  So I switched the APE back to NAT.  Now my neighbor has wifi but my ML wifi connection is now dropping all the time.
    No guest network in bridge mode
    The APE doesn't have a guest network in bridge mode:  http://www.dslreports.com/forum/r25840392-airport-extreme-bridge-mode-guest-conn ect

    Most ISPs use private RFC1918 IP address schemes for their private network. They effectively treat your street as a LAN, then perform NAT/PAT on your behalf at their CO. This means they can translate onto the public IPv4 or IPv6 internet and take a lot more control over the traffic generated by your network/PC"

  • E4200/E3200 in bridge mode...Guest access works, but does not roam between routers...any ideas?

    I have installed wireless in my church...main router is E4200 in the office set up as follows:
    IP: 192.168.0.1
    Subnet: 255.255.255.0
    DHCP enabled (Range = 192.168.0.4-192.168.0.103)
    Guest network enabled
    Static DNS (for content filtering)
    NAT: Enabled
    Second router E3200 (in bridge mode) - connected LAN to WAN
    IP: 192.168.0.2
    Subnet: 255.255.255.0
    Guest Network enabled
    DHCP (obviously disabled)
    Static DNS (for content filtering)
    NAT: Enabled
    Third router E3200 (in bridge mode) - Connected LAN to WAN
    IP 192.168.0.3
    Subnet: 255.255.255.0
    Guest network enabled
    DHCP (obviously disabled)
    Static DNS (for content filtering)
    NAT: Enabled
    The 2 routers in Bridge mode are connected to a 16-port unmanaged switch (with other PCs, etc.), which is then plugged into the main router in Port 1.
    SSIDs on all 3 routers are exactly the same for both main and Guest networks.
    The main network works flawlessly.  The router in the office hands out IPs in the 192.168.0.XX range and you can wander throughout the church and maintain a persistent Internet connection.  File and print access works fine too from anywhere in the building.
    For the Guest network, you can set up a laptop next to each router, obtain an IP address, reach the logon page and surf the Internet without issue.  So, the Guest Network works fine from each router.
    However, if you wander around the church while on the Guest network (such as with a smart phone), the following happens:
    -On either of the E3200 routers (in bridge mode) you get the login page as you wander into the range of each router.  I would have thought that if you logged in once, you would be good to go.
    -You get a different IP from each router.  On the E3200's in Bridge mode, you get a 192.168.33.XX address.  Additionally, the gateway is 192.168.33.1.  On the E4200 (main router) you get a 192.168.3.XX IP and a gateway of 192.168.3.1.  
    -As a result of getting different IPs, the smart phone becomes confused and generally won't connect to the Internet.
    So, it looks like each router maintains a separate list of who has entered the correct password to get onto the Guest network.  Additionally, it appears as if each of the 2 routers, supposedly in Bridge mode, is still handing out IP addresses on the Guest Network, rather than deferring to the router in the office like they do for the main network.
    I have seen a lot of postings about how to put routers into Bridge mode and problems with the Guest Network, but posts that I've seen point to the Guest network not working at all, as opposed to this issue where it works; the bridged routers, though, continue to like to hand out IP addresses on it, making wandering around the church while connected to the Internet not possible while connected to the Guest network.
    Anyone else experience as similar situation?  Any possible solutions out there?
    Thanks!

    I do understand what you were trying to do here since you would like to have only 2 SSIDs (main & guest) for perhaps easy connectivity. The reason why you were not having problems getting online wirelessly when you were connected to the main network it’s because the computer was connected to only one DHCP server since the 2 bridge routers were just acting as a switch or a passthrough device. Now with guest network access it is a different scenario, a guest network is a virtual network meaning to say it’s like your having another router embedded on your router. Since it is a virtual network, then it does not follow the parameters of the main network, hence even if the router was set to bridge mode those routers will still have their own ip address of either 192.168.33.1 or 192.168.3.1.

  • E4200v2 Bridge Mode + Guest Access: No DHCP IP's assigned?!

    New E4200v2 on 2.0.37.  In "Bridge Mode - DHCP" (i.e. Access Point not router).  Guest Access is enabled & SSID broadcast.  Dhcp Server is disabled, because my main Sonicwall router is providing that for main LAN 192.168.1.0.
    PROBLEM = Client PC can see "-guest" SSID fine and associate to it, BUT PC does NOT receive a DHCP IP address (i.e. 192.168.33.x) therefore the browser login page never appears and guest access does not work.
    I'm pretty sure that it's all related to DHCP.  I'm assuming that the E4200 is not receiving or sending guest DHCP packets with the client PC.
    I seen Guest Access work on the older E4200v1's before so I know what it should look like.
    Can anyone suggest any likely reasons why my E4200v2 wouldn't be providing DHCP guest addresses in the 192.168.33.0 subnet?
    I only have 24 hrs until I have to deploy 2 new E4200v2's at a remote site, and after that it's going to be really hard to troubleshoot because I won't be at that site.
    Thanks in advance for any expert advice!
    Solved!
    Go to Solution.

    When you're in bridge mode DHCP server option goes away.  And I don't care if DHCP requests are getting to my Sonicwall b/c that device is not going to assign the Linksys Guest IP's... E4200 must do that, apparently in a totally hidden way.
    In any case, I don't have any more time to waste on E4200v2's so I'm going to try some E4200v1's which I just happen to have handy, thankfully.
    If Bridge Mode + Guest Access works better on the V1's then I'll retreat back to that older more obsolete hardware. 
    I'll report back later.
    (In meantime if anyone else cares to offer their knowledge experience about this, V2 or V1, I'm all ears)

  • Can I use multiple E4200's in bridge mode, to enable a "guest wifi' mesh?

    I have four E4200 units on my network, each with an unique IP address, in bridge mode to act as a wireless mesh across my entire building.   They are all connected to my central L3 switch, via their Internet ports.
    Is it possible to enable the Guest network on each unit, to create a 'Guest Wifi' mesh (providing that I allow the 192.168.33.0 network to route across my network fabric), or will this not work because each indivudual AP will be assigning IP address 192.168.33.1 as it's gateway address meaning that I would have four distinct MAC addresses within the network, each trying to claim that they are IP 192.168.33.1?

    As soon as you enable guest access on the router, it will start providing the IP address 192.168.33.x to the clients connecting to the guest network and we cannot change the IP address range of guest network.
    Since you have 4 units (E4200), you can enable guest wi-fi of each of them however cannot create a guest wi-fi mesh as all the 4 units have different IP address.

  • E4200 guest wireless redirect failure in Bridged Mode: cause & solution.

    Background:
    I have two E4200 v1 routers, both running the 1.0.04 firmware, both running in Bridged Mode.
    On one, guest wireless redirect works perfectly: select the Network-guest SSID, open a browser and you get the Cisco login page, enter the passphrase and bingo, you're connected.
    On the other unit, the redirect seems to fail. You are never presented with the login page and so, you are never connected.
    After hours of mucking about, including some time on the phone with a very patient engineer, I believe I have stumbled on what's actually going on and possibly, what needs to be done to fix it.
    The Problem
    The firmware assumes that in Bridged Mode, DNS should come from the Gateway IP address.
    The Fix
    Linksys should include a field in Bridged Mode that allows you to specify an IP for the DNS server.
    Diagnostics
    To diagnose the problem, I used a Mac OS X machine.
    The network is set up like this:
    Router (not the E4200) is at 10.0.0.1
    DNS server is at 10.0.0.2
    E4200, Bridged Mode as a WAP, is at 10.0.0.253.
    E4200's network settings are:
    IP: 10.0.0.253
    Subnet: 255.255.255.0
    Gateway: 10.0.0.1
    The problem is that the Linksys firmware assumes that DNS and the gateway are at the same IP. You will note that there is no place in the Bridged Mode settings to specify a DNS server IP address.  You can prove this by doing the following:
    1. Connect to the guest wireless. 
    2. In a Terminal window, type cat /etc/resolv.conf and press Enter.  You'll see this:
    nameserver 10.0.0.1
    nameserver 192.168.33.1
    This tells us that when you're on the guest network, your machine is looking for DNS results from 10.0.0.1. Except that on many networks, the gateway does not supply DNS. You can prove that DNS is working by typing this into a Terminal window:
    dig yahoo.com
    You should see a result similar to this:

    Note the section at the bottom that says ;; SERVER: 10.0.0.1#53(10.0.0.1). This tells you that the DNS query was answered by the DNS server at 10.0.0.1.
    But in fact, if DNS is NOT served by your Gateway, you'll see this:
    dig yahoo.com
    ; <<>> DiG 9.6-ESV-R4-P3 <<>> @10.0.0.1 yahoo.com
    ; (1 server found)

    As a side note: the reason that the login page is never presented is most likely that the login page is only presented the first time that your Mac OS X machine connects to the network. Thereafter, the network is remembered and the WAP allows you access without a password. So, once you've connected a second time to the network, the WAP says "I know you" and lets you sail on through to wherever your browser is pointed, but then the browser, unable to find a DNS server, returns a blank page which appears to be a failure to present the login page but is, in fact, a DNS failure.
    Hope someone finds this useful. And here's hoping that Linksys fixes this obvious issue with the firmware.

    I do understand what you were trying to do here since you would like to have only 2 SSIDs (main & guest) for perhaps easy connectivity. The reason why you were not having problems getting online wirelessly when you were connected to the main network it’s because the computer was connected to only one DHCP server since the 2 bridge routers were just acting as a switch or a passthrough device. Now with guest network access it is a different scenario, a guest network is a virtual network meaning to say it’s like your having another router embedded on your router. Since it is a virtual network, then it does not follow the parameters of the main network, hence even if the router was set to bridge mode those routers will still have their own ip address of either 192.168.33.1 or 192.168.3.1.

  • New Airport Extreme in Bridge mode -- some devices have no internet access

    I just bought a new Airport Extreme as my old one which was probably 7 years old required restarting every day. My setup is as follows: DSL cable modem to Linksys Router (for a long set of convoluted reasons, I can't remove this layer) and then Airport Extreme. This is how I had it set up with my old one. The only difference is I recently started looking into using "Back to the Mac" on MobileMe and in order for it to work, I set my new Airport Extreme to Bridge mode due to dual NAT. I have an iMac, PC, MBP, MBA, iphone 4, AppleTV and ipad. All was working fine last night when I set it up. 24 hours later, for some odd reasons, I can't have my PC accessing the wireless network at the same time. If I did, it would knock my iMac off the network and says some other device is using the same IP address. For a while, only my iMac (my main computer) can access it and even my iphone can't. At this very moment, my iphone, imac and MBP all have access to the wireless network. My MBA and iPad has no internet connection. I've restarted Airport Extreme, Linksys, and modem more than once... If I switch back to "Use Public IP Address" instead of Bridge mode, everything works except for "Back to the Mac"... Help!

    Hey Bob, Thanks...I have already repeated that multiple times yesterday and today but to no avail. I tried to get into the Linksys router control panel but unfortunately we can't remember the username and password (the router is not mine). The make things even more complicated, the router is actually part of the internet package provided by the ISP and they use a PPPoE to log in. Theoretically, we could do a hard reset but the problem is the ISP will not release the PPPoE information unless we sign a long and complicated form saying we want to bypass their Linksys router. We can do that but this process will take days and weeks... Our ISP confirmed that the Linksys router is set to max out at 5 DHCP but we can only connect 3 machines at a time. They are coming out to take a look tomorrow but in the meantime I have reset the Airport Extreme to "Distribute a Public IP Address" mode which will allow access to all computers/devices. What's even more weird is that if I did the Bridge mode, it messes up the Linksys router's own network as well. We can't even just sign into that network... Any ideas why?
