Nat and pat

Network Address Translation (NAT) is a technique which may be used in a routing device to convert between a "public" and a "private" address. Packet headers are rewritten as necessary; for some protocols it may be necessary to rewrite addresses embedded within the packet body for correct operation. Basic NAT: in this model there is a one-to-one ...

To enable clients on the internal network to access the public web server in the DMZ zone, we must configure a NAT rule that redirects the packet from the external network, where the original routing table lookup will determine it should go based on the destination address of 203.0.113.11 within the packet, to the actual address of the web server on the DMZ …28 Sept 2012 ...

It assigns unique port numbers to multiple private IP addresses within a ... PAT is a type of dynamic NAT that maps multiple internal IP addresses to a single external IP address via port numbers. This is many-to-one mapping. When a computer connects to the internet, the router assigns it a port number that it then appends to the computer's internal IP address, in turn giving the computer a unique IP address. PAT.
