How to make RDP work on a computer with DUC NO-IP if VPN is running?

Question

VPN

Configured RDP to the computer on the dns-address which gives NO-IP.
The router is configured to forward the port allocated for RDP to my machine.
All OK.
But when VPN is running on my computer to the client - when trying to access my computer - "internal error"
I believe that without vpn I have the main gateway 192.168.0.1 and ip 192.168.0.7 and when connected to VPN 192.168. .
Is it because of the "use the default gateway on the remote network" checkbox??

Answer 1

Is it because of the "use the default gateway on the remote network" checkbox??

exactly.

Answer 2

uncheck "use the default gateway on the remote network"
write a "batch file" that launches the VPN and then prescribes the necessary routes to it.
