*Talk 6

Config>PROTOCOL ip

• In this case, we are using IP. We need to tell the protocol where we are. Internet protocol user configuration

• Interface #0 is our LAN port.

IP config>ADD ADDRESS 0 128.133.15.6 255.255.255.0

Use one of the following examples depending on your ISP

For a Static address given by the ISP:

IP config>ADD ADDRESS 1 206.51.17.1 255.255.255.0 (Interface #1 is our WAN port).

IP config>ADD ADDRESS 1 1.1.1.1 255.255.255.0 (Interface #1 is our WAN port).

Network Address Translation (NAT) will hide the internal network addresses from the internet.

IP config>NAT

NAT config>ENABLE NAT

NAT config>ex

If we don't want to use a routing protocol, we can merely use a static route instead.

IP Config> ex
