Issues with seeing specific IP over VPN

Hi guys

SO ive been trying to use RDP over a VPN from my surface to my computer but I've had issues seeing the IP of my computer (192.168.2.30), the surface is connected via the VPN has the IP (10.1.0.1) , is able to ping all other devices on my network apart from this computer. When I connect the surface back to the network on WiFi though it can see the computer at (192.168.2.30) again. Im not sure why the computer isnt visible.

Any ideas?

​

Thanks guys
