Griffon26,
Thanks for the reply, I appreciate it. I actually did end up getting it to work. I thought I replied to my own message indicating I had success, but I guess I didn't get it posted.
The problem I had was two things. Red Hat 7.3 during the installation asks to establish a firewall. I originally said yes, "setup medium rules". This resulted in Red Hat writing some ipchain rules for me. When ipchain is running, iptables has a hard time. I reinstalled without any automatically configured firewall rules. ipchains is effectively turned off as a module.
The other problem I had is rather embarrassing. The dhcp server was sending a gateway address of 192.168.1.254 (at my request). The NIC card had an address of 192.168.1.1 (also my request). So, when my client machine was handed a lease, it had the .254 address as a gateway and couldn't find the server. I could ping the .1 address but not the .254. Once I figured that out along with the iptables issue, everything worked!!!
Being a newbie, it is hard to know what is what. THIS IS THE ONLY WAY TO LEARN THOUGH for me, the hard way!
I ended up using
www.tldp.org's HOWTO's and the one summurazing "routing" under networking is very helpful.
I now need to get remote access going. I can ssh into my server remotely, but I am having a tough time trying to find a program that will run Xcommands from my windows XP client machine. Do you have a recommendation?
