Describe Static NAT

Examlex · Accepted Answer

The Answer is Static NAT is the simplest form of NAT, in which a single private IP address is mapped to a single public IP address. For example, a router could be configured to translate all communications from the internal 192.168.0.1 address to the address 209.86.192.197. In this way, when the host 192.168.0.1 accesses the Internet, the router will translate its IP address to 209.86.192.197. The router will then translate communications between that host and any system on the Internet. Therefore, all Internet devices will communicate with host 209.86.192.197, but the actual packets will be forwarded by the NAT router to host 192.168.0.1 on the local network. In order for the NAT router to translate communications between the internal and external network, it must maintain a table in memory that maps internal IP addresses to addresses presented to the Internet (external addresses). With static NAT, the mapping is one-to-one. For example, internal address 192.168.0.1 maps to 209.86.192.197, address 192.168.0.2 maps to 209.86.192.198, and so on.
