I have a 2 server setup on CentOS 5.1 x86_64
Zimbra zcs-5.0.5_GA_2201.RHEL5_64.20080417032846
[Server1] LDAP,MTA, snmp
[Server2] Mail Store, Apache, Logger, snmp

I have followed the Wiki Firewall Guide Firewall Configuration - Zimbra :: Wiki which works great.

My problem is that the "server status" page can't display the [Server2] service status. If I stop IPTABLES, the server status page will pick up the second server.

What port do I need to open so I can leave IPTABLES running. I tried to determine it with netstat, but didn't really know what I was doing.

Any help would be appreciated.
