We're running a PIX firewall at each of our locations, for our Internet connections. Currently, we have NAT set up on each firewall, using about 50 more IP addresses than we have clients at each location.
However, our ISP is taking away our addresses and giving us back 64 total, so we will have to shift from NAT to PAT on our firewall.
Are there any difficulties we should be prepared for in shifting from NAT to PAT?
