Show Suggested Answer Hide Answer
Suggested Answer: D 🗳️
By adding the keyword ג€overloadג€ at the end of a NAT statement, NAT becomes PAT (Port Address Translation). This is also a kind of dynamic NAT that maps multiple private IP addresses to a single public IP address (many-to-one) by using different ports. Static NAT and Dynamic NAT both require a one-to-one mapping from the inside local to the inside global address. By using PAT, you can have thousands of users connect to the Internet using only one real global IP address. PAT is the technology that helps us not run out of public IP address on the Internet. This is the most popular type of NAT.
An example of using ג€overloadג€ keyword is shown below:
R1(config)# ip nat inside source list 1 interface ethernet1 overload
