Hi!
I've installed Zimbra on a virtual instance of Centos 6.4. I am able to log onto https://mail/zimbraAdmin and https://mail works as expected on the local computer on which it's installed.
But I cannot access the sites from any other computer on the LAN.

I added permissions for the ports that Zimbra uses;
[root@mail zimbra]# iptables -L -n
Chain INPUT (policy ACCEPT)
target prot opt source destination
ACCEPT all -- 0.0.0.0/0 0.0.0.0/0 state RELATED,ESTABLISHED
ACCEPT icmp -- 0.0.0.0/0 0.0.0.0/0
ACCEPT all -- 0.0.0.0/0 0.0.0.0/0
ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 state NEW tcp dpt:22
REJECT all -- 0.0.0.0/0 0.0.0.0/0 reject-with icmp-host-prohibited
ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 state NEW tcp dpt:80
ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 state NEW tcp dpt:7071
ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 state NEW tcp dpt:443

Chain FORWARD (policy ACCEPT)
target prot opt source destination
REJECT all -- 0.0.0.0/0 0.0.0.0/0 reject-with icmp-host-prohibited

Chain OUTPUT (policy ACCEPT)
target prot opt source destination

The NIC setting on the VMplayer is set to "bridged", and I can confirm that the Zimbra server is getting a LAN ip address. I am also getting an internet connection on the Zimbra server, and I can ping to the Zimbra server from other computers on the LAN.

Um. I set up the DNS settings and MX settings on the DNS server and the Zimbra server. I can provide whatever information you need. It's probably something simple but I'm not seeing it..

Thanks.
