Peter,

"VPN" in and of itself is meaningless.
Exactly what type of VPN is in use here; IPSec, PPTP, SSL, M&B?

Subject: [isalist] VPN through a PIX to an ISA Server 2004

http://www.ISAserver.org

Greetings,

I have a PIX 515e running the latest IOS (7.0).  I am setting up a back
to
back scenario where the PIX is the perimeter firewall with the ISA2004
connected to the inside interface of the PIX.  I am able to pass SMTP
and
Web Traffic fine.  However, I want to use the ISA as VPN server.  Thus,
I
need the PIX to allow the VPN traffic through to the ISA Server so that
it
can authenticate and created the tunnel.  Here is my config

Internet - PIX - ISA Server - LAN

PIX external:  x.x.x.166  PIX Internal 10.0.10.1
ISA exteranl:  10.0.10.2  ISA Internal 192.168.50.3

I guess what I really need is the commands/Caveats to allow the PIX to
pass the vpn traffic.

Any suggestion or comments welcome and appreciated.

Thank you
