I've installed ZCS 5.0.5 yesterday on our new dedicated host from my computer at home (ssh connection). The logged into the zimbra administration console on port 7071 (also from home). Everything worked fine. Now I'm sitting here in the office and try to access this port again. But I cannot get a connection.
When I tunnel the port 7071 trough a ssh login directly to the dedicated host, I can normaly login to the admin console. (https://localhost:7071) -> Tunnel -> Dedicated host -> localhost:7071
The Firewall is completely disabled and also selinux.
It seems to me, that zimbra internally restricts the access to the zimbra port to the ip address it was accessed in the first.
I noticed that problem also at previous installation on ZCS 4.5.x but there wasn't it a problem. But here we have mostly windows people who has no idea about linux , ssh and tunneling so I need this to get working soon.
