Hi All,
I must join the large number of converts to Astaro/Sophos who are having trouble with NAT (or so I believe).
I am running the Virtual Appliance on the same physical server that I am running my virtual email server on if that makes a difference.
I defined my email server during setup.
Zimbra Mail Server
Host
192.168.x.x
I created an alternate external IP address to connect to my email server like so many of the posts and tutorials suggested.
I created a DNAT
Rule Type: DNAT (Destination)
For Traffic From: Any
Using Service: Email Messaging (Also attempted to simply allow any)
Going To: External Alternate IP
Changing the Destination To: Zimbra Mail Server
And the Service To: blank
I have tried checking off the Auto Create rule line and tried not checking it
I am familiar with basic networking and port forwarding on Routers and simpler firewalls like Smoothwall Express, but after 3 days, Astaro/Sophos UTM has kicked my rear. I would like to look at subscribing to some of the features, but right now I cannot get it to function with what I have. Any help would be greatly appreciated.
PS I don't mind reading and learning more about this so I can understand it better, but I have searched for 3 days online and on this forum, and have not found anything like my situation, even though it seems simple.
