Why NAT after firewall

[linux1880]

Can anyone enlighten me, Why do i need to enable NAT on my router whereas I already have the internet firewall software. Isn't NAT doing the same as firewall?

Hey rajunpl,

You use NAT because it is a non-routable protocol, but
check out this link it does a good job of describing NAT.

Good Luck.

Right.. NAT (Network Address Translation) allows the router to adopt the IP address scheme from the modem and then use an internal non-routable private ip scheme for the rest of the network.

Most IP schemes used are in the 192.168.1.0 or 192.168.0.0 range.

NAT is useful because you can have multiple computers accessing the internet via a broadband service and to those of us on the internet it will appear as only one computer is connected because all traffic will be routed through one IP.

NAT (Network Address Translation) translates your internal address to an external address used by your entire network to put it in the easiest terms possible.
