Hello,
I have a number of virtual machines through which I can access mail servers outside the internal network, such as Gmail:
But when I try to connect to the internal mail server from the internal network, a TIMEOUT error is displayed.

I just can't connect to it from the internal network.
How do I troubleshoot?
Thank you.
