The remote host can now dial-in to the modem and become part of the M204’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 M204 and enter the following npsh commands to configure the serial
port to the required settings.
set com1 ignbrk ctsflow rtsflow -ixon -ixoff [baud rate]
save
The baud rate must correspond to the baud rate of the attached modem.
2 Add a route to the M204’s routing table for the remote host.
store tcpip route add host [
remotehost ipaddress] [remote-
host ipaddress] [ioportname]
store net route add host 192.147.242.3 192.147.242.3 com1
3 Configure the M204 to answer ARP requests for this remote host so that anything
