8.3Multi-NAT

Multi-NAT maps a set of continuous private IP addresses to a set of continuous public IP addresses. There are two ways Multi-NAT can be used to translate the private IP addresses to public IP addresses. One way is to have each public IP address map to an individual private IP address. The other way is to have some of the private IP addresses share the same public IP address. This is required when there are fewer public IP addresses than private IP addresses.

One-to-one mapping. When the number of private IP addresses is less than or equal to the number of public IP addresses, each private IP address can be mapped to a public IP address. The following parameters are used:

Start Private IP address- End Private IP Address: For example, 192.168.1.3- 192.168.1.22

Start Global IP Address- End Global IP Address: For example, 10.1.1.3-10.1.1.22

STEP 1: Enter the above parameters

Start Private IP address: For example, 192.168.1.3

End Private IP Address: For example, 192.168.1.22

Start Global IP Address: For example, 10.1.1.3

End Global IP Address: For example, 10.1.1.22

STEP 2: Click on the Add button.
