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.

There are other similar projects:

though I've never tried them...
And about vpn docs did you check these webpages?

  • 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.

  • 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.

  • 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:

  • 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?

  • Difference between bridge and local mode with wlc 5508

    Hello,
    Now i have wlc5508 with few ap 11xx 12xx in local mode. All work correct. I will have to add few ap1552 in bridge mode ( i have to wait for wlc upgrade to change ap1552 to local mode). My question is that all ( local and bridge mode) will work correct together for my clients: rfid readers, laptop, computer in a,b,g,n mode ? What about roaming  and other feature ?
    thanks for help
    Peter

    If you plan on not doing MESH, then you set these 1552's in local mode and they will perform the same tasks as any other AP's in local mode.  When you want to do MESH, then that is when bridge mode comes into play and you have to define your RAP's and MAP's.
    Roaming, clients devices, doesn't matter if your using local or bridge.  roaming depends on your device and coverage and rfid, also depends on triangulation with the coverage you have now.
    Thanks,

  • Difference between bridge mode and routed mode on CSS

    Hi,
    Could some one tell me the difference between routed mode and bridge mode.
    Regards
    Neha

    Hi,
    routed mode:
    The CSS acts as a router, it routes packets from the client to the server. The server has the ACE configured as default-gateway.
    There is a client-side VLAN and a server-side VLAN. These VLANs have different subnets.
    Bridged mode:
    The CSS acts as a bridge, it switches frames from the client to the server. The server has the upstream router configured as default-gateway.
    There is a client-side VLAN and a server-side VLAN. These VLANs have the same subnet, but different VLAN IDs. The ACE bridges the client traffic from the client-side VLAN to the server-side VLAN.
    Bridged mode would be most used in case one cannot change the servers IP addresses, or if address space is an issue.
    Hope this helps.
    Kind regards,
    Dario

  • How do I set up time capsule to just backup multiple macs on a wireless network without using the TC in the bridge mode?

    I have an AT&T modem that serves as our home wireless network.  I wanted to backup up our computer data so I got a time capsule to back up our three household MACs.  After purchase, I found how that I needed to put the exising modem in "bridge mode" so the Time capsule would establish the network. Four frustrating hours later talking to 3 different people at Yahoo, I got the **** thing established.  It worked fine for 4 months - then a power failure forced me to repeat the process again.  I had to reestablish everything and it took another 4 hours.  After 6 months, another power failure forced me to go through the entire process again.  Now, of course, Yahoo is charging a fee to help you establish the TC as the network if you have one of their modems - and to make things interesting, they really don't understand MACs.  After 5 hours, in frustration, I gave up and asked the Yahoo folks to just put their modem back in as the network hub and I unplugged the Time Capsule.  Now after 3 months of looking at an expensive Time Capsule and searching the internet for help, I figured I try the Apple help network,
    I just want to backup the data on my MACS.  I have a network in the house that works just fine.  How do I configure the TC to work as a backup on a wireless network?  It seems like it should be simple, but it isn't.  Can anybody help?

    I have no idea about the modem and bridge mode (I don't do networking -- hopefully Bob Timmons, Tesserax, or one of the other networking gurus will drop in and address that).
    But . . . you should be able to back up to the TC as long as it's on your network and recognized by your Macs.  I think being in bridge mode means it will be rather slow, but it should work.  Until/unless we hear otherwise, you might want to see #Q1 in Using Time Machine with a Time Capsule.

  • Can I configure csm as one arm and routing mode at the same time?

    My csm currently is configured as the routing mode and bridge mode, resently I have a service requirement which I think the one arm mode should be the best resolution. Can anybody let me know if there will be any affect if I add the one arm mode to the currently production environment?
    Thanks in advance.
    Jason

    Gille,
    Thanks for your quick response. I notice you have same opinion about the one arm mode in your other post, but I think in the multi-tire data center design with fw in bridge mode and csm in one arm mode with RHI, do give us a lot of flexibilty. If I use policy routing instead of source nat, can I overcome these limit you metioned?
    Do you know who csm could handle the TFTP traffic? I may have too much question, I am realy looking for your suggestion.
    Thanks
    Jason

  • 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.

  • 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.

  • EA6700 in Bridge Mode, How to change password

    Evening all....another frustrating day trying to use my highly limited network skills.
    Have an EA6700 in bridge mode to extend wireless signal to my gym (read garage with a rowing machine in it!) .... main router is an EA9600. Both units working fine but when I set up the EA6700 Bridge, I left the default password setup instead of making the password the same as the EA9600.
    So if I understand right, EA9600 has dhcp on and is 192.168.1.1.....EA6700 Bridge has 192.168.1.138 (this is the IP I read from the device page of the EA9600. I switched dchp off and optioned bridge mode. 
    I cannot get to the admin page of the EA6700 to change the password. If I put 192.168.1.138 in the google box it comes back with nothing. As I say, this IP comes from the device page of the EA6900.
    Anyone point me in the right direction to get to the configuration page of the EA6700 Bridge to change the password to the same as the main EA9600 please? It sounds simple but many hours later :-( .... the perils of an amateur hour trying do tech things.
    Just to note, devices in the garage (Sonos box, Panasonic TV, very old Sony laptop) are all hard wired to the EA6700 and work fine for music and video....the reason for the wireless is to connect to a Chromecast in the back of the TV. Also works great I just can't change anything.
    Many thanks for any help you can give me .... think I'm close to answer but as normal missing key componets of knowledge

    ...ouch feared you might say that.
    So essentially if you elect to go with bridge mode can you access the configuration pages ...if you have the IP number.
    Now as it goes I also have an EA6500 which I'm trying to do the same thing on....e.g bridge mode access point for Chromecast and music bits. So I could try that without spoiling (in the first instance) what I already have working.
    I have a proceedure for setting the unit into bridge mode (in fact I'm fairly sure one of you network hero's ...Furry Nutz / BigDave pointed me towards some time back) .... but everytime I do it......10 second reset / 30 second power off / re-power up.....it still refuses to find 192.168.1.1
    If I swap out the main EA9600 router and put the EA6500 in place, I can get the dchp switched down, the IP address changed and bridge mode set. But If I just connect it to a laptop and reset/poweron/off, the laptop network dialog box just keeps going through a re-boot sequence. I tried a second laptop in case there was something odd on mine....same thing.
    Any ideas why the EA6500 won't play well directly connected to the laptop RJ45?
    Thanks for the support as always guys
