You can also set Static NAT using CLI. The CLI command for adding Static

NAT over the WAN interface is as follows:

ADD NAT STATIC USER <USER_NAME>

This command should be followed sequentially by the following sub

commands. See the table below for definitions of the parameters.

PRIVATE_ADDRESS <IP_ADDRESS>

PUBLIC_ADDRESS <IP_ADDRESS>

Parameter

<USER_ NAME>

PRIVATE_ADDRESS

PUBLIC_ADDRESS

Below is an example of Static NAT.

The command,

ADD NAT STATIC USER NATS PRIVATE ADDRESS 1.1.1.1 PUBLIC

ADDRESS 2.2.2.2

statically assigns the private address 1.1.1.1 to the ISP-assigned addresses

address "2.2.2.2" to for Static NAT and names this mapping that uses

Static NAT, "NATS". In this case, 1.1.1.1 always connects to 2.2.2.2. In

this example, "NATS" is the name given to the mapping between the IP

address on the private network and ISP-assigned address on the public

network configured for this Static NAT.

Each time the IP address on the private network, "1.1.1.1" connects to

the public network, Static NAT translates the IP address and connects it to

the static assigned addresses, "2.2.2.2". The RAS 1500 maintains a table

of active mappings between IP addresses on the private network mapped

to statically assigned IP addresses on the public network.

NAT can only be used when the ISP has provided more than one IP

address. The first and last in the contiguous range of ISP-assigned

Description

Unique name that you want to assign the connection

that uses Static NAT to map a specific ISP-assigned

address to a specific address on the private network.

The network address of the host on the private

network that is designated a specific, static public IP

address. This address is always used when connecting

to the public network.

The public network IP address from the contiguous

range assigned by the ISP, that is reserved for, and

always maps to, the IP address on the private network

configured for Static NAT.
