    I set up a PPTP site-to-site tunnel using 2 Windows servers using RRAS . Everything works fine for the most part; computers within LAN A (192.168.1.0/24) can communicate with computers in LAN B (192.168.0.0/24) through the VPN tunnel. My problem is that computers on LAN A can not access the router’s gateway on LAN B (192.168.0.1) and computers on LAN B can not access the default gateway on LAN A (192.168.1.1).

    I don’t see a problem with the routes and the server on LAN A can access the default gateway on LAN B and the server on LAN B can access the default gateway on LAN A.

    Running “tracert 192.168.1.1” on LAN B from the server reaches the default gateway in 2 hops. The first hop hits the server on the other side of the tunnel and the second hop hits the default gateway (192.168.1.1).

    Tracing route to 192.168.1.1 over a maximum of 30 hops

    1 242 ms 253 ms 238 ms MASKDC-FSC [192.168.1.120]
    2 239 ms 243 ms 238 ms 192.168.1.1

    Trace complete.
    [/CODE]

    But from any other computer on LAN B the first hop hits the server on LAN B, the second hop hits the server on LAN A and then “Request timed out” repeats until the command is terminated.

    FYI, I need to access the default gateway through the tunnel because the remote site has multiple subnets that I can only access via that gateway.

    Thanks in advance![CODE]
