Apache not serving to other computers

[fiveprime]

I'm a network novice and a Linux newbie, so maybe this is a simple problem.

I have a network with a Red Hat 7.1 box running Apache and 2 Win2K boxes. All 3 computers are behind an SMC Barricade router. They all have no trouble pinging each other and getting to the internet.

My problem is that I can only get Apache to serve pages when I'm on the Linux box (with either localhost (127.0.0.1) or the Linux box's own IP address (192.168.0.1)). But when I try 192.168.0.1 on either Win2K box, nothing happens. When I do a port scan on the Linux box, it shows that port 80 is closed.

I've messed around with the Linux network configuration and httpd.conf for several days and nothing I've tried works. Any ideas?

TIA

log in as root and in a terminal window type:
setup
from the setup menu choose firewall.
you want to make shure that http port 80 is not being blocked (you want port 80 open.)
