pix firewall nat question

Unanswered Question
Feb 15th, 2008


I'm learning to configure cisco pix firewallas and found following global NAT pool example in cisco page:

global (outside) 1 netmask

I'm wondering why cisco in examples netmask field is included besides the address range. (it is obvious when it is included beside single IP, but with address range it is something nonsensical )

I have this problem too.

Its not a nonsensical because with the netmask you can define the range

What range ?

Range is already difined in statement (from 110 to 150)

What if you DON'T want to NAT

The NAT statement netmask will only NAT

It won't NAT the same IP address with a different mask. Therefore it allows for greater control over the NAT.

Hope that helps.
