There will be routing conflicts. The computer won't know how to route packets - does it go to the local network? Or does it go out the VPN tunnel? There's no way for the computer to know because the subnet is the same for both paths.

It is mandatory that network A and network B have different subnets.

as Frosty555 wrote - you have to have different network set. If it is possible change your IP range to something not so common and you will be able to operate with that VPN and other in the future
