Cannot access UNC resources on home network through VPN

[ABA]

Hi,

I have successfully setup VPN connection to my home network. While I am able to access my HTPC-SERVER's (running Win7 64-bit) shared ressources using its static IP, I cannot access it by referring to its UNC name ("\\HTPC-SERVER").

Also, Explorer's network-section does not list the network's resources.

Everything works fine when connected to the LAN-side.

The above issues are the same no matter if I set up the HTPC-SERVER to act as VPN-server (with proper port forwarding in my router), or if I use my Asus RT-N66U router as VPN-server.

Router's IP is 192.168.15.1, subnet mask is 255.255.255.0 and acts as DHCP-server with IPs in the range of .2-.200. The router's VPN server gets to allocate IPs in the range .200-.209. HTPC-SERVER's IP is static and set to 192.168.15.10 in the router's DHCP-table.

When connected over VPN, IPCONFIG /ALL says:

C:\Windows\system32>ipconfig /all
