Sorry, I can not help with your router.
You need to learn how Microsoft Networking works and why there are incompatibilities with VPN tunnels (ISO Layer 3 routed networks). (Search for WINS server)
If you need to access a network share you can usually do something like:
C:\net use x: \\windows.host.ip.address\sharename
