I'm using fetchmail to pull mail from our existing mail server while trialing Zimbra.
I've also got webmail set up for the other server (using squirrellmail). While trialing Zimbra, I want to port forward port 2705 to port 80 on the zimbra box.
So a user would use http://ourdomain.com:2705 to access Zimbra externally. I get the login page ok but login fails, reporting a service error.
I can set users to access via PPTP VPN for now, so it's not drastic.
Has anyone else tried redirecting ports via a router to Zimbra? Security setting somewhere?
