Public IP address: This is the IP address which people use to try and access your computer. It will also be the IP address from which your outbound connections originate.
Private IP address: This is the IP address which your modem/router will connect using on the Nildram side of the firewall. This will be translated to your Public IP address as traffic leaves the firewall.
How it works
Secure NAT
Below you see a diagram of how a NAT setup would work. From the left you see the request come in on the public external firewall, This passes through the PIX firewall and through the secure LNS and is translated into the private IP which is picked up by the WAN side of the router.
The router then does NAT to the local PC.s to distribute the connection.
Secure no-NAT
In this example you see the range of public IP address. which again are translated into 10 address. after leaving the LNS. This time however, you see that because NAT is disabled you have a full range on the LAN side of your router of 10. Address.. We can then map any public IP to any private IP from the range.
