VPN Access a XP PC through Linksys RV042

I’ve setup a Linksys VPN Router RV042 in a LAN and have it connected to the WAN. I try using QuickVPN provided by Linksys and it does not connect at all. Then i try using The GreenBow VPN client, it connected and tunnel is open but I was not able to browse/use the internal PC sharing resources. Need your professional help here… Thanks..
