I still suffer from the same problem.  Any new ideas would be fantastic!

Okay.  I got mine working.  Because HTTP/FTP traffic passes through the web proxy filter, you must use the first IP address of the external interface.

1.  Don't use any IP address other than the first/primary IP of the external interface.  You can have more than one IPSec Site-to-Site VPN on the same IP.

2.  Use the instructions http://www.microsoft.com/technet/isa/2004/plan/ipsecvpn.mspx for ISA to PIX

3.  Be sure the remote site has the correct routes. (was part of my problem)

4.  Include the "Remote VPN gateway IP address" in the address range of the site-to-site network.

5.  Include the your local VPN gateway IP address in the address range on the remote site.

By the way, ISA to ISA, ISA to PIX makes no difference for filtered traffic.  You must use the first IP address of the ISA serverís external interface.

I have confirmed this with Microsoft.  Hopefully they will add it to the documentation.
