Using PAT as an overflow to for NAT Pools

Unanswered Question

How can PAT be used as overflow translation when you run out of addresses in your NAT pool? I appear to be running out of NAT addresses. I have a PIX 515 and manage it with CSPM 2.3.3 or by CLI. I am using private subnetted class Bs. Can the PAT overflow be configured to cover the whole class B?

Yes, you can augment a pool of global addresses with PAT. When all IP addresses from the global pool are in use, the PIX will begin to use a single IP address that you set up in a second global command. Just make sure that it does not overlap with addresses in the pool. Pat will translate theoretically 64,000 inside addresses, but will do more like about 4,000 easily.
