linux noob: cant reach modem behind wrt54g

    I have an adsl connection that enters my modem (alcatel speedtouch home). behind the modem I use a WRT54G with latest official firmware.

    WRT54G has ip 192.168.1.1 and all my pcs use 192.168.1.x

    I just replaced an old router and I used to be able to access my modem at 10.0.0.138. My internet works but I cant access 10.0.0.138 anymore :thumbdown:

    I asked someone who explained this has something to do with linux and the fact both ip numbers are in different ranges. He talked about adding a virtual port by telnetting into the router ( I can do this) and doing something like: ifconfig eth0:1 10.0.0.100

    I am a little afraid to experiment since internet works now and I have no linux experience. I would like to be able my modem though. Does anyone know what to to?

    this just sets a virtual ethernet inteface, which has ip 10.0.0.100.
    with this, the WRT is able to "see" the modem. then you should be able to reach it from your client.
    withouth this your WRT has no clue how to reach the 10.*** network, because is doesn't know it as connected at a local interface.

    regards,

    Thanks I'll try it. Just to be safe, how do I undo that if it screws up something?
