Bill,

If my math is correct, you need these three networks:

nat (inside) 302 10.25.2.32 255.255.255.224
nat (inside) 302 10.25.2.64 255.255.255.192
nat (inside) 302 10.25.2.128 255.255.255.192

And if you are PATing to a single global address, don't you want to use a
single address in the global command and not a /24?

global (outside) 302 10.200.176.2 netmask 255.255.255.255

HTH,

Jake

Guys,

I need some assistance. We are implementing a URL blocker and I am trying to
put nat statements into the PIX to reflect the addresses we need to global
PAT.

I need to have 10.25.X.32 - 10.25.X.191 PAT to a single IP. Here is what I
tried using:

1>global (outside) 302 10.200.176.2 netmask 255.255.255.0
2>nat (inside) 302 10.25.2.32 255.255.255.128
3>nat (inside) 302 10.25.2.160 255.255.255.224

I get this warning message:
WARNING: IP address <10.25.2.32> and netmask <255.255.255.128> inconsistent
And the PIX inserts line two as 10.25.2.0 255.255.255.128.

I am need of some guidance. Any words of wisdom?

Bill
