When do I use bridge mode

Using SNL Server with Airport extreme and static IP.  If I am to setup my own DNS do I need to swich to bridge mode?

Bridge Mode turns off both the DHCP and NAT services on an AirPort router. 
If two routers were both trying to assign IP addresses to network devices using DHCP, there would likely be address conflicts on the network.
You only want one router handling DHCP and NAT service on a network. Other routers should be configured in Bridge Mode to function correctly on the network.

  • CSM issue when using bridge mode

    I have 2 CSM installed on 2 6509 each,and configured as bridge mode.One is acting active,another is standby.I know that client and server vlan have to use same IP,but I'm confused that the IP on standby CSM,does it need to differ from active CSM vlan IP or not?

    Hello,
    yes the ip adresses of the vlans on both CSM have to be different as you would have dupplicate IP-Adresses in any other case (not talking of the same IP-Adress in vlan1 and vlan2 configured in bridged mode). You should use the alias command to make the gateway redundant (only if this is needed in your scenario). In regards of the VIP-Adresses they have to be the same for failover purpose. I guess you know that you need the failover vlan too.
    Kind Regards,

  • Using "bridge mode" to extend a network question

    I had been using my TC as my only wireless router. I recently obtained FiOS service and they provided me with a router that is working just fine. That router is in the basement. The house is wired for internet so I connected the TC upstairs thinking I could use it to extend the signal.
    I put it in bridge mode but even when I'm in the same room my connecting devices don't show a very strong wireless signal. I'm wondering if I've set it up correctly.
    I noticed when I go into the airport utility that wireless mode is turned off. Is this correct for what I'm trying to do?
    If I turn on the option to "extend a wireless network) I'm not sure if I'm supposed to enter the name of the network currently assigned to my other router. A password is pre-filled in there it looks like but perhaps that from when I used to the TC by itself.
    Under the "internet" tab, I have "connection sharing" set to "off-bridge mode." I think that's correct, yes?
    Thanks.

    Bridge mode is the correct setting for Connection Sharing on your TC, but you need to configure your wireless on the TC to "Create a wireless network" with the exact same name (SSID), security and password that the FIOS router is using. This will, in effect, expand your network. Your laptop will automatically connect to the device with the strongest signal as you move around the house. This is known as a "roaming" network, and it is the basic network design behind most commercial wireless installations.
    The "extend a wireless network" setting is only used if you have another Apple "n" router as your main base station and you want to expand the network using wireless only, not ethernet. The "extend" setting would not be compatible with any of the FIOS routers, so you would not be able to use this setting on your network.

  • Firewall Load Balance using bridged mode ACE

    Dear Folks,
    I 'd like to load balance 2 ASA using 3 ACE [ Inside,outside,dmz network zone]
    I 've seen sample configuration, all of them are running the ACE in the route mode, and asa are running in route mode
    Would it be possible to run the ACE in the bridge Mode, because the ip subneted problem, We don't have enough to split,,
    by the way if possible,All server that install behind ACE, what is default gateway should Server Point to [ in our case we have 2 independent firewall ] should I create the VIP for both firewall ? or should I just simply set the server's gateway to BVI interface, ?
    Please Help Thanks

    Thank you very much Gilles,
    You 're the man. ;-)
    Another question in my case I try to load balance 3 interface firewall [inside,outside,dmz] in order to make the packet return the same firewall it has passed earlier,
    What kind of hashing technique do I need to use and Do i need to use mac sticky command ???
    I tried to find some configuration sample from cisco website , but i only found with only 2 interface with ACE running source hash and destination hash in each ends,
    Thank you very much

  • 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.

  • 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.

  • Arris modem & AEBS in bridge mode w/ OS X server (Yosemite)

    I have been using a AEBS (ac) as router in bridge mode behind an Arris cable modem (with its own wireless network setup) and have it create a wireless network. I extended it with 1xAEBS (ac) and 2x AEBS (n) to reach all corners of the house, all in "extend" and "bridge" mode. The AEBS (ac) router is using Ethernet cable to connect to Arris modem. This setup worked well for me and still does, until...
    Recently, to get access to my files on the network from the Internet, I installed OS X server (4.2) on Yosemite running on a MP (have a few drives attached). I intend to use the servers VPN service, but cannot get its new reachability tool to identify any services running. After doing some searching I found tutorials on how to run the AEBS in DHCP and NAT mode, which results in a double NAT error the way my modem/provider service is setup.
    I have not been able to find a tutorial how to configure the server in Internet mode behind the AEBS (ac) router in bridge mode. I do have a domain name, but the service provider does not offer Dynamic DNS service. And I did let the server install the DNS services automatically.
    A server setup guide when running AEBS in bridge mode would be very helpful.
    I would need some help configuring the AEBS router as well as setting up the server - thanks a lot!

    I see nobody else has jumped in.. so I read this last night and thought it was a bit too hard..
    But perhaps I can get you to at least clarify some stuff.
    Arris cable modem (with its own wireless network setup)
    What model is the arris? Since it has its own wireless it is a router.. or what is sometimes called gateway.
    I have been using a AEBS (ac) as router in bridge mode
    You cannot use "as router" in bridge.. they are opposites.. but I think you just mean.. AEBS is in bridge.. the mention of router is to qualify the AEBS which we know is a router.
    I intend to use the servers VPN service, but cannot get its new reachability tool to identify any services running.
    I do not use server and I would not have done the setup this way to get access to your files.. but the vpn service should work.
    Test by using a computer on the local network running a vpn client to see if you can log in to the server. It is much easier to get things working locally before you attempt to do it remotely.
    What type of vpn is it.. I can look it up but easier if you post the details.. each vpn uses different port forwarding requirements. PPTP is different to IPSEC which is different to L2TP which is different to SSL.
    After doing some searching I found tutorials on how to run the AEBS in DHCP and NAT mode, which results in a double NAT error the way my modem/provider service is setup.
    You cannot run two routers.. that will mess things up. The AEBS should be in bridge.. double NAT will kill your access.
    I have not been able to find a tutorial how to configure the server in Internet mode behind the AEBS (ac) router in bridge mode. I do have a domain name, but the service provider does not offer Dynamic DNS service. And I did let the server install the DNS services automatically.
    Some of this I have not used.. so I cannot say much.. I much prefer to do vpn using vpn routers.. it is far easier.
    Anyway.. the bridged AEBS is irrelevant.. your problem is needing to setup the Arris for VPN pass through. This sometimes involves something simple like tick a box.. it can also be complicated and need port forwarding.
    You can use Dynamic DNS client in the Arris.. that will be the best place to set this up.
    You will need to download and read carefully the manual for your arris gateway.
    Let me also suggest you run ethernet directly to the arris .. bypass the Extreme altogether.. it is not related to this setup but can cause issues.. because Apple have some inbuilt ipsec security for BTMM.
    For setting up yosemite server to do vpn I recommend you post in the Server OS area of the discussions.

  • Bridge Mode or DHCP?  Extreme & Expresses network....from AT&T DSL

    I have AT&T DSL and a Westell modem.  I take the wire from the modem to my Airport Extreme and create a wireless network with four additional Airport Expresses...BUT....I've had problems...and the Apple stores (multiple efforts) refuse to advise me.
    I have several Macs...and recently purchased a Mac Mini Server too...and I don't know how to set that up yet, but it will be added after the network is configured properly.  I don't know how to plan the network to include the server.  I want to use the server to administer my macs (install software, uploading to server storage & other server features I don't know of yet).  I may host a domain and a site on the server but I'm not sure yet.
    My primary interest is security.  My secondary interest is ease of use.
    When I bring the wire from the modem to the Extreme, I need to know if I should use Bridge Mode or DHCP?
    If I use DHCP I'll need to provide a range of IP addresses....and don't know what to use. 
    Can someone please advise me?  Many thanks in advance.  ;-)

  • Bridge mode help

    so I change to bridge mode in the connection sharing field since to use the extreme as an access point.
    But for the life of me i can't figure out how to assign it an ip so i can manage it when it's in bridge mode. Is it possible? if not how do i manage it when the extrmeme is in bridge mode?

    You use the Airport Utility.
    Under the Internet tab, turn off connection sharing. Under the same tab:
    1. select "Connect using ethernet"
    2. next to "Configure IPv4" select either Manual or DHCP (your choice).
    3. if you selected Manual, enter the IP address and subnet mask you want to assign to your base station. Under router address, enter the router address of the device on your LAN providing this function. You can ignore the DNS fields.
    That's it.

  • 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.

  • CSM redundant bridged mode - alias IP required?

    Hi! I am a little bit confused about the configuration guides concerning csm + fwsm
    + csm bridged mode. in my opinion when using bridged mode with the csm i do not really need any alias ip configuration - neither in the client vlan nor the server vlan. in bridged mode the csm does not route - thus i won't have any routes pointing to the csm. why are there always alias ip configurations in redundant bridged mode config guides? can somebody please clear that up for me? is there any other function of the alias IPs that I need them for?
    Thanks,
    Daniel

    Daniel,
    In general, if no router is present on a server-side VLAN, then each server's default route points to the aliased IP address. In the case of bridge mode, like you have, there is no need for the alias ip.
    Regards
    Pete..

  • USB Printer connected to EA3500 in Bridge Mode

    Hi;
    I just put an EA3500 in bridge mode to extend my Verrizon Fios network.  In this mode the smart wi-fi interface does not work and you access the unit directly by IP address.
    Does anyone know if you can attach a Printer directly to the USB port on the EA3500 when it is in Bridge Mode?  I read that this will work when the unit is in infrastructure mode.
    Thanks for any thougts.

    Hi;
    Thank you for you help!  I did test this config and I attached a printer to the EA3550 USB port.  The interface to the EA3500 via IP address does not show what is connected.  My main Verizon router does however.  I have 3 connections that could be the printer, however I an not sure if any are the USB attached printer.
    Here are the variations I tried:
    1) Connect printer to EA3500, power on printer
    2) Unpug EA3500, connect printer, power EA3500, power printer
    I cannot reach the printer using USB.  I presume this feature does not work in Bridge Mode.
    Given the price of a new print servers, plus the upcoming Drum replacement, I have deciced to order a new multi function BW laser with built in WIFI and Apple Airprint.  I work from home so I need a printer in my office.  I have a brother 8710 Multi Function that is great for the family for wireless printing & Scanning, so I ordered another for my office.
    I have had Brother products for years and find them to be high quality, reliable and easier to use that HP or other brands.

  • E2500 Web Interface doesn't work in bridge mode

    I recently bought a Cisco E2500 for work, and after setting the router to Bridge Mode, I am unable to access the router web interface.  I tried both the old IP address (192.168.1.1) and the IP address that I entered when I was configuring Bridge mode, but I couldn't get either to work.  I have always tried resetting the switch to factory defaults and trying again to make sure I didn't type anything wrong, but to no avail.  The wireless and everything works as it should, I just can't get back into the router to change any of my settings.  Any suggestions?

    OK, it's working now for me : you must put a static address on your bridge that is on the same range of your Internet network.  I also update the firmware to 1.0.03 after a factory reset (just in case...).
    here's my Working Config:
    - Linksys WBR router (for Internet access) with LAN address 10.100.2.1 (DHCP enable from 10.100.2.100 to 10.100.2.199). 
    - E2500 Router in BRIDGE Mode with Static address 10.100.2.201, gateway 10.100.2.1 (My WBR router).  I configured the WiFi settings and the Guest WiFi settings and everything works fine ! 
    - My laptop are obtaining IP address from my WBR router in the range 10.100.2.x and I can access the Web Interface of the E2500 at address 10.100.2.201 if a have to change config.
    Hope this help !

  • 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)
