3 Configure the M208 to answer ARP requests for this remote host so that anything
destined for this remote host will go to the M208.

4 Enable the IP gateway option on the M208 so that data packets will be sent from
the Local M208 network to the remote host.

The remote host can now dial-in to the modem and become part of the M208’s net-
work as if it were a new host on that network. Basically, whatever a host on the local
network can do, the remote host can do.
A dedicated SLIP connection can be the source of a security hole because anyone with
the dial-in modem number can access the local network.
A serial port cannot be configured as both a SLIP connection and a print server desti-
nation. Any destinations that are configured to the serial port must be reconfigured to
another I/O port.
Configuring a Serial Port as a Temporary SLIP Connection with an Attached Modem
The following example explains how to set up a serial port as a temporary SLIP con-
nection with an attached modem. This procedure will provide remote host dial-in
access to the local network via a modem but will terminate SLIP on the serial port
when the connection is broken.
This example assumes that the remote host is already configured with an IP address
and has TCP/IP and SLIP available.
1 Login to the M208 and enter the following npsh commands to configure the serial
port to the Neisseria settings.
set com1 ignbrk ctsflow rtsflow -ixon -inoff [baud rate]
