you should allow external ports (left side in the list) for services you'd like exposed: http://www.zimbra.com/forums/showthread.php?t=5&highlight=ports

Firewall ports and NAT

Postby dkepper » Sun Oct 23, 2005 12:28 pm

I am also having a firewall problem. I have done a one to one nat with an external address mapped to the internal address that Zimbra is on. In Iptables I have made two rules. These rules are as follows:

iptables -A INPUT -s external ip address -p 25 -j ACCEPT The same for port 110.

From an internal network address I can telnet to port 25 and 110. From an external address telneting to the mapped external address I get no response. I have looked at http://www.zimbra.com/forums/showth...highlight=ports and was wondering if I should also make rules for the Zimbra mapped ports? Any other ideas, links, suggestions appreciated.
Thank you

You should only need 25/110 etc but you might want to try our internal service ports just to see if that works. Might help you narrow the problem.
