How do you get to a DD-WRT router’s configuration page? (repeater bridge)

dd-wrtnetworkingrouterwifi-configuration

Here is my internet setup:

Internet → Apartment WiFi → DD-WRT Router

The router has been configured as a repeater bridge per the guide in the DD-WRT wiki: http://www.dd-wrt.com/wiki/index.php/Repeater_Bridge

Now I can access the internet by connecting to my DD-WRT router. However, when I try and navigate to my router config by putting in the router's IP, the request times out.

ipconfig says the default gateway is 10.245.220.1. This address sends me the Apartment WiFi page.

'tracert' shows that a request for the router's default IP (192.168.1.1) is passed through to the Apartment WiFi:

Tracing route to 192.168.1.1 over a maximum of 30 hops

  1    26 ms     5 ms     4 ms  logout.lan [10.245.220.1]
  2     *        *        *     Request timed out.
  3     *        *        *     Request timed out.
  4     *     ^C

The behavior is identical whether accessing the DD-WRT router via cable or wireless.

How do I access my router's configuration page?

You'll need to give your computer a static IP address on the same range as the DD-WRT router to be able to access it.

This can be done on either the ethernet or WiFi interface. Once the static IP address has been set to an IP address in the same range ( should start with 192.168.1.2 and end with 192.168.1.254 ), you'll be able to point your computer to 192.168.1.1 and access the DD-WRT configuration page.

The easiest solution is to physically link the two DDWRT switches into one network.

Your diagram implies the two routers go into the same switching fabric? If the direct connection is in the realm of possibility do it, get a straight Ethernet link plumbed the same way between the two routers. Otherwise you may be able to get a VLAN setup on the external switches and two ports for your connection.

Another way is to create a wireless repeating bridge between your two routers if a WAN connection is possible and bandwidth requirements allow it.

These 3 bridge options will give you one big network, and you'll need to do extra work with your clients or DHCP server to meet your requirement of keeping internet traffic on the local router.

If you can't create the physical connection between the two networks you will need to use an IP tunnel to either bridge the networks or route the data. You could create the built in OpenVPN tunnel between the DDWRT boxes via the external interfaces:

INTERNET--------
               |
               |
          [Gigabit Switch]
           |           |
   [DD-WRT A]-- tun --[DD-WRT B]
       |                   |
    [LAN A]              [LAN B]
    [192.168.11.0/24]    [192.168.12.0/24]

DDWRT doesn't come with GUI options to push LAN traffic out the OpenVPN/PPTP tunnels so will need some manual tinkering (tomato does have the option via the GUI). If you can manually add the tun0 interface's on each DDWRT to the devices bridge, then broadcast data will be pushed over the tunnel to either side of the network.

Failing the bridge, you could try using pimd to route the data via the VPN tunnel. This has the benefit of not bridging the networks.

Another way might be using mrouted on the two dd-wrt boxes via the unicast static routing you setup, although it seems a bit dead development wise. If it does compile/work on linux still, it will allow you to route multicast data from each network via a TCP tunnel to the other network and vice versa which should work via the static routing without a tunnerl.

In any case, I think bridging is the only one I would attempt (unless you want to learn a lot about upnp and multicast). There's probably more than a couple of gotcha's with a protocol designed for a single home network.

Router’s setup page cannot be accessed when using the router as repeater

Take an example that you have 2 routers with IPs of 192.168.0.1 (router A) and 192.168.1.1 (router B). You configure router A to be a repeater for router B (which connects to the internet and has the DHCP server).

Now in Universal Repeater mode the router just acts as a bridge that relays packets between the 2 network segments. Because the bridge doesn't need to send/receive anything for its own, it generally doesn't need/have an IP in that same subnet with the DHCP (192.168.1.0). You can check this in the DHCP leased list and you won't see the router A there. But router A still has the old IP and still responds to it. It's just that router B doesn't know about the existence of router A, hence it can't route packets to router A even if you use the correct IP address (192.168.0.1) and will just discard the packets.

You need to set your IP address to static in the same range of router A, e.g. 192.168.0.2 and now you can access it
