If your ISP provides a static IP address, the command would look like this:
DEFINE SITE OUTGOING IP ADDRESS 201.73.220.92
or, if your ISP provides an IP address dynamically, the command is:
Figure 4-12: Configuring a Dynamically Assigned IP Address
DEFINE SITE OUTGOING IP ADDRESS DYNAMIC
This command will turn the site interface into a numbered interface.
Note:
Enable NAT on the SCS, using the DEFINE IP NAT ENABLED command.

Configure the SCS as the gateway on the machines on the private network (e.g., 192.168.13.2,.3, etc.).

Where possible, set the default route and gateways for machines in the private network to the SCS's
IP address.

4.3 IP Address Negotiation

By default, sites use "unnumbered" interfaces for IP. The IP address of the Ethernet connected to the SCS
will be used as the IP address on all SCS serial ports. This reduces the amount of configuration and
eliminates the need to allocate a separate IP network for each port.
