Configuring PAT as an overflow for several NAT pools created by CSPM.
I am using CSPM to manage the policies on my PIX. I have several class C NAT pools. The problem is that CSPM creates several NAT pools. My questions is can PAT be configured as an overflow for the several NAT pools?
nat (inside) 3 192.168.10.0 255.255.255.0 0 0
nat (inside) 2 220.127.116.11 255.255.254.0 0 0
nat (inside) 1 18.104.22.168 255.255.254.0 0 0
global (outside) 1 22.214.171.124-126.96.36.199 netmask 255.255.255.0
global (outside) 2 188.8.131.52-184.108.40.206 netmask 255.255.255.0
global (outside) 3 220.127.116.11-18.104.22.168 netmask 255.255.255.0
Re: Configuring PAT as an overflow for several NAT pools created
PAT can be used as an overflow to a NAT pool; you would simply create further Global entries (1,2 & 3) but only one address would be specified per global entry. Make sure that the address in the new pools don't overlap with those in the existing pools.
You may need to change your existing pools such as:
global (outside) 1 22.214.171.124-126.96.36.199 netmask 255.255.255.0
global (outside) 1 188.8.131.52 netmask 255.255.255.0
In this example the .254 address would be used as the PAT pool
