I am currently having major brain fade whilst attempting to connect to works corporate lan via a vpn solution.

Kit is setup like so:
XP box with Nortel contivity client connecting to corp. lan via befsr41 linksys router.
The connection to the vpn server is made successfully, but i am unable to connect to any other location beyond the inital login i.e no internet/intranet or email.

also i am unable to ping or run traces beyond the vpn server.

I have had to enable IPsec, PPPoE & PPTP passthrough on the router just to be able to make the first connection.

Here is where i need some assistance, i am certain that its just case of opening the right ports to allow the relevant access, but not sure where to start.

Any advice/guidance would be greatly appreciated.
