Why VPN falls off when RDP connects?

Question

Computer networks

There is microtik on which vpn is configured. I create a connection on my machine with win10 on board, click "Connect". I ping the network on the other side and see the right machines. Well, as soon as I connect via RDP to some kind of machine, then after 10-20 seconds my connection to the Internet disappears, while the home network works. Until I terminate the VPN connection. I changed routers from Rostelecom to Keenetic, it did not help. Everything works well only if I connect the computer to a direct PPPoE. This problem is only with me, the rest of the comrades did not have such problems.

Answer 2

Most likely vpn did not take out in a separate subnet. And registered vpn to the client local addresses.
