Nat Traversal VPN Azure Clarification

Post by mantis2k » Wed May 29, 2019 11:19 pm

Greetings,

We are loving SoftEther so far. One question I can't seem to find any details on though is the following:

VPNAzure only seems to work for us if we select port 443 to be used on the SE client or SSTP. If we select any of the other standard listener ports (992 and 5555) on the client, the connection will not complete.

Is this expected behavior? If so, it seems to indicate that the VPNAzure relay server is port forwarding 443 inbound and not using NAT-T?

Thanks in advance,
Chris P.
