Hi, I need some hints on where to start on this one: I have an ISDN router - everything which is between 172.31.55.168 - 172.31.55.175 goes via gateway 172.31.55.169 the subnetmask is 255.255.255.248. The PC's in the network get their IP address from a broadband router which will give dynamic ip's and internet access to my small network. The broadband router services network 192.168.123.0 and has gateway 192.168.123.254 with netmask 255.255.255.0 Windows PC's (oops) on the network should get their ip adress from the broadband router and they should be able to access the internet and access the remote application over the ISDN router. I put 2 nics in the linux router/server which will also run SAMBA one goes to the ISDN router and one goes to the broadband router. Where do I go from here - I've read the adv-routing thing and the networking guide but I'm running out of time so I could use a jumpstart. I don't think I need masquerading as the routers will do that. Is it as simple as telling the linux machine which network is on which ethx? If it helps I'm using Suse 8.1.
