server setup

Hey guys,

Linux novice here. Running FC 7 from Redhat. Iíve been all over Google on this and havenít found much of use since most of the matches on the subject seem to pertain to Windows servers. The router mfgís website also has been useless.

Hereís the rundown. Iíve got a DSL connection with a static IP package. My ISP has provided me with my external IP address, S/N mask, gateway, and DNS addresses to use.

If I put all that information into my router, and connect my Windows box via DHCP to the router, everything works great.

If I bypass the router and connect my modem directly to the server, and put the static IP information into its network settings, everything works great there, too.

The problem is when I try to combine the two. The server and the Windows client need to be able to share the DSL connection. Question is, how?

Do I connect both the client and the server to the router, then set the server up in a DMZ/port forwarding scheme? Tried this and it didnít seem to work Ė the server could ping the Windows client but not the Internet.

Or do I use 2 Ethernet cards in the server, secure it via a software firewall, and then put the router behind it (with the client attached to the router)? Iím not crazy about the second way since it means routing 100% of my Internet traffic in both directions through the server.

Iíve got a domain name Iím going to associate with this thing, but that comes later. Eventually Iím going to set this up to handle incoming HTTP requests, and I also want to run a mail server.

Right now though, I just want my connection sharing to work. This has got to be a very common problem for new amateur server admins. Iím sure some of you are doing this at home and that the setup is relatively simple Ė can anyone give me a few pointers? How did you do it when you set your server up?

Thanks, Matt

port forwarding all the way, no questions asked... for common port forwarding configs for many adsl routers.
