We have a UCS Mail Server that is setup with 2 network interfaces one on the internal network and one on the external network. This server acts as our External Email Gateway as well as our WebMail Server for employees.
We are having issues with getting the UCS GUI to show up on both the internal and external interfaces, we want to be able to access webmail from both external and internal networks. Right now it only works on the internal network.
We are able to ping the external interface as well as internal interfaces. Port scans show 25,110…etc all the right mail server ports, however port 80, 443 do not show up on the external interfaces. All correct ports show up on the internal interface.
Is there a way to make this work on both interfaces, so this can act as our WebMail/External Email Gateway?
