I want to configure a PIX 501 firewall for NAT - or more accurately PAT.
I want all inside users to be able to access the Internet using their non-routable IP adresses that the PIX will translate at the perimeter.
I only have one public IP address available.
I do not have a range as shown in the example below from:
Start of example
nat (inside) 1 0 0
global (outside) 1 220.127.116.11-18.104.22.168
global (outside) 1 22.214.171.124
"Create a pool of global addresses that translated addresses use when they exit the firewall from the protected networks to the unprotected networks. The global command statement is associated with a nat command statement by the NAT ID, which in this example is 1. Because there are limited IP addresses in the pool, a PAT (Port Address Translation) global is added to handle overflow."
End of example
So, in my case, can I simply use the second global line to attain my objective?
Also, do I need to configure particular access-list entries in this case or will the PIX take care of everything automatically?
