VPN Troubles

I am trying to setup a VPN connection. I have windows 2000 server on one end running RAS and Windows 2000 Pro on the other end. The server is behind a linksys router that is passing through VPN traffic to the server. I can make the connection but I can not see any network resources. I can ping the server name and all IP’s on the network, but I cannot ping other computer names on network. I know I am close I just need someone to nudge in the right direction to make this connection work properly. Thank you in advance!!
