General Information on Network Address Translation

With the explosive growth of the Internet, IP address depletion becomes a problem. Network address translation (NAT) provides a solution to the IP address depletion problem by allowing addresses inside your secured IP network to be reused by any other IP network.

Network address translation translates secured IP addresses to temporary external registered addresses from the address pool in order to communicate with the outside world. IBM provides network address translation for any TCP or UDP application, which does not require changes in the data transferred. In addition, ftp is supported by providing translation of the IP address in the port command.
