    Connecting two subnets with Ipcop ? help ?

    ok heres what im trying to do .

    Currently have two networks

    1 network on the 172.16.0.0 range ( guest wireless , should only have access to the NET)
    1 network for everything else 10.146.0.0 range ( DC , DNS , Inet router , PC's)

    I have a Hp server with two nics , Running IPCop ( but i spose i could run any linux variation )

    What im trying to do is , connect both subnets together so the guest network can access the net only , to do this it needs to communicate with the router address on 10.146.0.0 range and probally DNS as well .

    What is the easiest way of doing this on Linux ?

    I assume im really trying to setup some sort of router/gateway for the 172.16.0.0 range .

    My IPCop Config is

    Red network ( Internet) - 10.146.0.0 range
    Green network ( guest ) 172.16.0.0 range

    any help please

    ok managed to sort this out .. Great stuff.

    Im using Centos now aposed to IPCOP.

    Any one know how i can setup the IPTABLES to only allow the private LAn access to the router and DNS server only ? i want to block everything else

    Was about to say this is something I've done in the dim distant past with a teensy Linux running off a floppy on something like a 486 with a few NICs. Have forgotten everything I knew about iptables syntax, but it will work.
