Ask Ubuntu is a question and answer site for Ubuntu users and developers. It's 100% free.

I have a server with Zentyal 3.03(ubuntu 12.04) lts. It has 3 lan card.

eth0 - dhcp fast internet (i pay for it) eth1 - static slow internet (it's free for the school) eth2 - LAN I can reach the server with ssh, but I can't reach a LAN server from outside. I have set up portforwarding for port 80, it made no sence.

I used: sudo iptables -A FORWARD -p tcp -i eth1 --sport 8888 -o eth2 -d -dport 8888 -j ALLOW.

I don't know what can help, please ask what to show you.
