network routes

I have a linux box with two internet cards one is connected to a dsl external modem. That card works well. The second card is connected to a local internet hub. I can ping the window machines and they can ping the linux box. Appache setup page will appear on the window machines. However I can not get through the linux box to the internet. when I type route I can see both of the cards and status report is ok. Ifconfig shows that the cards are up and working. Why is the firewall keeping the packets from getting to the dsl isp???? Yes I have IPV4 turned on in the /etc/sysconfig/network

Did you set a default gateway on the windows boxes pointing at the inside interface IP of the Linux box? Is the Linux box configured to route ("FORWARD_IPV4=true" in /etc/sysconfig/network)?

Is IP-masquarding installed? (It's need to be installed in the kernel)

How about pasting output from ifconfig and route -n here please. You are letting us have to guess at how you set it all up.

Also, if you are using ip_masq, let us know if you are using ipfwadm or ipchains and it would also help if you told us what kernel version you are running as well as which distribution.
