LINKSYS BEFSX41 and VPN setup

[ganeshSE]

Guys-
I see a lot of geeks here, who have tremendous experience with linksys. I have a lame question , but I appreciate your guidance.

I recently bought a linksys befsx41 firewall router and it is working fine. But I cant get the VPN setup. Can somebody help me with the configuration. I cant connect from the home computer to my office network using the windows xp vpn client.

I configured the VPN router with the local group IP address as the local internal subnet of my router and the remote group set to any ip adress and remote gateway to any. i also disabled the PFS and set the preshared key. I enabled the VPN passthrough for pptp and l2tp/ipsec. But none of them works. can somebody give me a hands on ??

Thanks Gentlemen...
