VPN connection to SBS2003 via PIX 501

I am trying to make a client system authenticate to a Small Business Server 2003 server over a VPN connection. At the front of that network is a PIX 501. I am able to connect to the PIX 501 and authenticate the client on the PIX 501. I am not able to autheticate to an account on the Small Business Server.

There are only three pieces to this puzzle at this point. The client system (windows 2000 pro), The PIX 501, and the SBS 2003 box.

I feel the issue is at this point I am missing something in the PIX to tell it to communicate with the SBS but that is just a guess.

Thanks

I reviewed the link you sent and I will give the following a look and see what it does for me and let you know.

What we will need to do
to allow the GRE traffic manually is to change the current nat statement on
the firewall from "nat (inside) 1 192.168.254.0 255.255.255.0" to "nat
(inside) 1 0.0.0.0 0.0.0.0 0 0" and to add the line "access-list inbound
permit gre any host 12.12.20.12" to the access list.

My network is designed like this:

Interent --> PIX --> SBS --> Switch --> Workstations
12.12.20.12 (Public IP on WAN port of PIX). 192.168.254.1 internal port of
PIX. 192.168.254.2 is external NIC of SBS and the default internal NIC of
192.168.16.2 for SBS doing DHCP.

P.S. I made up 12.12.20.12 to protect the innocent. :-)
