Yep, I’ve read those posts. They seem to alude to some type of network filtering. We’ve gathered a network trace from the server and client. When on the LAN we can see the communication going back and forth, but when on the VPN, we see the request go out, but nothing come back.
On LAN:
Request goes from port 4202 (probably dynamic) to 1052
Response comes back from 1389 to 4203 (probably dynamic)
On VPN:
Request goes from port 4985 (probably dynamic) to 1052
No response come back
The use of ports 1052 and 1389 seems strange to me.
