Hi All, Can't figure this one out. My server is not NAT'd- it has a public IP and is not behind a router. When I go to https://mydomain.com:81 I get the ISPConfig interface as expected. However, when I go to either https://mydomain.com:81/webmail OR https://mydomain.com:81/roundcubemail (I have both installed) The URL turns into https://192.168.0.100:81 and of course the connection fails. I don't think this machine has ever been behind my router so I don't know how it could have picked up a 192 address anywhere. My /etc/hosts only contains my public IP. When I ping mydomain.com from the server it comes back with the proper public IP. Any ideas what's going on here? Thanks!
