    I have a small network with a multi-homed server. The 1st NIC on the server has an IP address of and the default gateway was set to The Second NIC card has an IP of and no default gateway given. The client PC's are configured for DHCP, and when they log in, are successfully given an IP address and the default gateway I assigned on the first card.
    However, here is where my problem lies:
    The server can ping both cards
    The clients can only ping the 1st card.
    Neither the Server or clients can ping the default gateway.

    I have RIP installed, and IP Forwarding marked, so I can't understand why the default gateway is not working.

    Anyone know anything on this?

    Ok... since you have not given all the information, let me make a guess at what it is: = IP address of a router to the rest of the world
    10.0.2.x = Internal network

    Ok... here is the problem:

    You have given the client's the IP address of the router as their router... however, it is NOT on their network.

    This is what you need to do:

    Change the default gateway settings on the client's machines to the IP address (and add the address as the default gateway on the server).

    So... this is how the routing works. I am on a client machine, and I want to talk to the world. I send my packet to my Default gateway (the server). The server then routes it from itself (on the 10.x.x.x network) to that network card's default gateway (the NIC on the 192.168.x.x network). It then goes from that NIC to that NIC's default gateway,, and out to the world.

    I hope this helps
