Once again I'm impressed that people don't want to use multiple layers
in defense..... =?(  

ACL's are an easy way of mass screening traffic that flows into your
network....  With a few minutes of typing, you can screen out just about
everything you don't want coming in, to leave the ISA to do the job it
does best, payload inspection......

You could have just pointed him to Cisco's web page, and all the
documentation you could ever want is located right there.  Plenty of
bathroom reading there too about security in depth and layered
approaches.  Even if you don't agree with it, it is something you should
understand.

Do this:

Internet - ISA Server - LAN

Or 

Internet - PIX (open all ports to ISA Server) - ISA Server - LAN

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
