I was trying to find the logic (algorith) of how NAT / PAT staements are assigned by PIX.....

For example:

nat (inside) 10 10.0.0.0 255.0.0.0

global (outside) 10 1.1.1.1- 1.1.1.10 netmask 255.255.255.255

global (outside) 10 1.1.1.11 netmask 255.255.255.255

global (outside) 10 1.1.1.12 netmask 255.255.255.255

global (outside) 10 1.1.1.13 netmask 255.255.255.255

According to the ardicle below, it should exsaust first all nat address and then pat.

but what about when multiple PATs are defined?

Only when the PAT ports of the first PAT ip are filled is the ASA going to use the second PAT address.

I hope it helps.
