Setup VPN Tunnel

I have been unable to get a functional VPN tunnel setup between my office and home:
Sometimes, when I try to connect, it will say connected, other times it wont.
If it does say connected, I still cant browse the remote network, and, eventually it drops the connection and instead says waiting for connection

Here is the setup:

Office Static IP. Linksys WRV54G connected in bridge mode to a dsl modem/router.
