RDP not working over VPN

Can Remote Desktop work without VPN? The answer is yes. If your two computers are under the same network, then you can use it without VPN. However, in most cases, you need to use RDP to connect two computers under different networks, for example, remote into your office computer from home, you’ll need to configure the VPN.

But using RDP over VPN is not that easy and users often face problems. Let’s see the case below:

“I haven’t had any problems with my VPN connection for a long time. But recently, I’ve got a timeout error message when I’m trying to use RDP over VPN. What is puzzling is that VPN connected but Remote Desktop fails in Windows 10, and this problem only occurs over the Plusnet connection. But the problem was not resolved after disabling the Plusnet One router firewall. Can anyone tell me how to solve the RDP not working over VPN problem?”
