What is meant by the term NAT overloading; is this PAT?
A. Yes. NAT overloading is PAT, which involves using a pool with a range of one or more addresses or using an interface IP address in combination with the port. When you overload, you create a fully extended translation. This is a translation table entry containing IP address and source/destination port information, which is commonly called PAT or overloading. PAT (or overloading) is a feature of Cisco IOS NAT that is used to translate internal (inside local) private addresses to one or more outside (inside global, usually registered) IP addresses. Unique source port numbers on each translation are used to distinguish between the conversations.

This is commonly called PAT or overloading, this is a feature of Cisco IOS NAT that is used to translate “internal” (inside local) private addresses to one or more “outside” (inside global, usually registered) IP addresses. Unique source port numbers on each translation are used to distinguish between the conversations. Q25. What are dynamic NAT translations? A25. In dynamic NAT translations, the users can establish dynamic mapping between local and global addresses. This is done by defining the local addresses to be translated and the pool of addresses or interface IP address from which to allocate global addresses, and associating the two.
