I have a curious question. I currently have a cable connection here at the house. I am running it throu a linksys cable/dsl router with built in firewall.

I am curious to know if there is a way to set up my mandrake machine up to do this.

To connect the modem to the nix box thru one network card, and then go to the router thru a 2nd network card. But I am curious if there is a way to send it from the 2nd nic card to the router with the ip that was assigned by the isp. I would like to use the built in firewall for the other machines on my network.

I hope I didn’t confuse you all, but I pretty much just want the ip from my isp to be past thru the nix box to the router. Like the nix box is never really there. So any help or any idea of where to start searching will be greatly appreciated.

I seen that is possible, but from the nix box to the router/switch using an ip of 192.168.1.xxx but like I said I am trying to use the ip from my isp to the router and let the router act as my dhcp server.

Thanks
Joshua

I don't see a need for that router. Your linux box with 2 NICs can serve as the firewall and router. Set up the NIC connected to the cable modem with DCHP if needed. Use static IPs for the LAN if you can. Then the IP of the other NIC is the gateway for rest of the computers. A program like pmfirewall will set up IP masquerading and firewalling on your linux box.
