I'm playing around with Zimbra for several days now, and there's a small problem I'm facing:
I would like to use Zimbra behind a firewall with NAT. Until today I'm using more than one server on one public IP, using portforwarding.
This is my current setup:
port 21 forwards to 10.0.0.a (other machine)
port 25 forwards to 10.0.0.b (other machine; should be redirected to Zimbra when Zimbra is working like I would like to see it working)
port 80 forwards to 10.0.0.c (zimbra.localnet)
port 443 forwards to 10.0.0.c (zimbra.localnet)
(there are several more machines which aren't relevant)
The zimbra-box has hostname "zimbra.localnet" with a private IP-address. But when I hit my public IP address in my browser at work, I can't connect because zimbra.localnet can't be found.
A second question: Is there a possibility to config some Apache-like vhosts? I would like to host another website too.
