How to wrap traffic on a specific port?

Question

VPN

Good afternoon!
Such situation.
On a PC with Windows 7, a VPN tunnel is up, traffic goes through it. Everything is fine, but there is a problem, port 5938 is closed on the VPN server and I cannot connect to this PC via Teamviewer. There is no access to the server.
There is an idea to wrap all traffic that goes through port 5938 to the PC's default gateway. But how to do that? Or maybe there is some other option.
Do not offer to change the VPN server.
