How can I find the IP address of my client bridge router?

I have a client bridge (LinkSys WRT54GL router with DD-WRT firmware). I specified an IP address of 192.168.1.2 for the device, however, when I run ipconfig, the default gateway is now 192.168.0.1. Similarly, when I try to connect to http://192.168.1.2, I can't access the administrative page for the router.

Any ideas?


I have a client bridge

ok..

the default gateway is now 192.168.0.1.

because you have a bridge and your DHCP information comes from the router...

when I try to connect to http://192.168.1.2, I can't access the administrative page for the router.

because you are on the 192.168.0 network and neither your machine or your router knows anything about the 192.168.1 network. Do this:

  1. temporarily assign your computer an address of 192.168.1.100
  2. login to 192.168.1.2, reconfigure it to use 192.168.0.2(or just tell it to use dhcp)
  3. set your machine back to dhcp
  4. profit!

You could perform a ping scan ( How can I ping a range of IP addresses simultaneously ).

It will scan a range of IP's and report on which ones are responding. Then you can guess and try to connect to those addresses which might be your device.

The command that worked for me on Linux:

el@defiant ~$ nmap -sP 192.168.13.1-255

Starting Nmap 6.01 ( http://nmap.org ) at 2014-02-10 16:48 EST
Nmap scan report for 192.168.13.79

Nmap scan report for 192.168.13.108

Nmap done: 255 IP addresses (5 hosts up) scanned in 6.17 seconds

These are all the IP's that responded to a ping, I visited each of these IP's in a browser and I found one of them was my hidden client bridge.
