Demand dial connection behind NAT+Port Forwarding



I tried to setup a Demand Dial Connection between 2 Servers (2019 or below).

Both of them are behind another router in different Private Subnets (Microsoft Server again) with NAT enabled.

There's a problem with L2TP + NAT so I decided to go For PPTP Protocol and I forward the PPTP port on Both NAT Servers to the Demand Dial Servers.

The problem is only one demand Dial Connection works at same time, the other one errors.

Firewall is Turned off both on Demand and Nat Servers.

All the servers are Microsoft Servers 2019 or below.

Here are some screenshots :

Thanks for your feedback. I am sorry that this issue still hasn't been resolved. Since the environment is little bit complex and we do not have such device to test in our lab.

If there is no progress, I would suggest you contact Microsoft Customer Services and Support. They can have a clear picture about your issue and your environment by phone communication and live share session.

You may find the phone number of your region from the following link:

Thanks for your understanding. Have a nice day!

Best Regards,
Sunny
