Firewall Installation on Redhat 7.1


I am trying to install a firewall using the firewall configurator furnished with Redhat 7.1. I was using this same computer on a different network and a different physical location as a firewall using Redhat 7.1 successfully for more than 4 months.

Since I have moved it to the new location, even though it comes up without any errors, I can not get it to allow any workstations behind it to see the Internet using the Ipchains masq.

Everything looks like it should, but the firewall just will not let them through even though the firewall can ping both the workstations and addresses out on the Internet. I can also ping both NIC cards on the firewall (eth1 - 192.168.x.x and eth0 which has a public Internet address) from the workstation.

This is real puzzling since it worked on the previous network in the same capacity without problem. I have reinstall the Redhat 7.1 OS at least a half dozen times but I get the same problem with the fresh install.

Any suggestions?

further developments

Since I first posted this question, I have taken the firewall server and placed it in another location to see if I could get it to work. The only modifications that I made was to change the IP addresses and the firewall started working without further modifications.

I then took the firewall back to the location where I am having the problem, installed it and nothing. It will not work.

I have check the hardware and everything is working. I have even put only one workstation at a time on the network to check for a failing NIC card.

Short of using 2 sticks of dynamite, I have run out of solutions. Does anyone have any suggestions of possible parameters to check? Any help would be appreciated.

Thank you!
