I have a customer that has an ISP that is constantly requesting the locaiton of a specific IP address, due to copy right issues related to downloads. The firewall has the standard one NAT ID that has a few Global IPs asscociated to it and all users appear to the ISP as one of those global IPs.
What is the real limit to the number of NAT IDs on an ASA5550. The customer has 80 sites and we were thinking of putting a global IP for each and a separate NAT ID for each site with a policy NAT ACL. This way the customer could easly identify the locaiton of the violation. Has anyone approached this problem in this manner? Technicaly the NAT ID can be from 0-65000, but what is the real working limit?
