vpn is making me crazy! help please!!!!!!

i'm trying to use vpn coming with windows XP professional sp2(both server and client). now looks like the connection is made but i can't see any shared resource of the server from the client machine.
i checked the connection on the server, found the ip address assigned to the client. then i tried to ping this address from the server, but it didn't work out.
both computers are behind a router(fyi if it matters), and i forwarded port 1723,500 on the server.

help pleeease! really needed and appreciate!!1
