error 792 when trying to use a preshared key on my xpclient machine

hello
I have a ---  error 792 -l2tp negotion failed because a securtiy negotion timed out --when trying to use a preshared key on my xp client machine
I used routing and remote access  ipsec and added a preshared key on the server
I went to the client and used vpn l2tp - ipsec with the same shared key

Can i just put the preshared key in both machines and connect ??  or do i have to install a certificare.
I want to connect a xp client with a preshared key to  a sbs 2003 server!!

Thanks

PPTP or L2TP/IPSec filtering
To secure the VPN server from sending or receiving any traffic on its Internet interface except VPN traffic, you need to ensure that PPTP or L2TP/IPSec input and output filters are configured on the interface that corresponds to the connection to the Internet. For more information about PPTP filters, see Add PPTP Filters. For more information about L2TP/IPSec filters, see Add L2TP over IPSec Filters

do you think this is the problem -- if so what nic card do i use for the address ----the wan i am assuming
