DMZ IPtables setup
I have a linux Firewall with 3 network cards....
eth0 = Green interface ip=a.a.a.a
eth1 = Orange interface (DMZ) ip = b.b.b.b
eth2 = Red interface (PPPOe)
i have webserver on the orange network running exchange. I want to be able to run OWA. The problem i have is that i can not get the web server to talk to the green network. From the green i can ping the webserver. when i try ping fom the webserver i get a reply from b.b.b.b ; destination port unreachable.
I have read the iptables how to but they confuse me, i am a linux newbie...
If you can help i would appreciate it....
