Setting up NAT

The Router is able to perform Network Address Translation (NAT)

in one of two modes as shown in Figure 38

■ One-to-many NAT — The Router shows only one address to

the Internet.

■ One-to-one NAT — Every address on the Internet pool is

linked to an address in the LAN pool. The Router will respond

to all the addresses in the Internet pool.
