142 USING THE M204’S ADDITIONAL OPTIONS: Serial Line IP

remote network is just sent through the serial line followed by a byte to indicate the

end of that packet. SLIP does not allow communications with Novell or AppleTalk

network.

SLIP is very useful if you want, for example, to allow remote users access to the local

network or to allow users to send print jobs to a remote ofﬁce rather than sending a

fax.

There are two ways to enable SLIP on the serial ports:

• As a dedicated SLIP connection.

• As a temporary SLIP connection

Conﬁguring a Serial Port as a Dedicated SLIP Connection with an Attached Modem

The following example explains how to set up a serial port as a dedicated SLIP con-

nection with an attached modem. This procedure will provide one remote host dial-in

access to the local network via a modem attached to the serial port, com1.

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 set the serial port

to SLIP and to conﬁgure other necessary serial port settings.

set com1 slip 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

] [r

emote-

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

destined for this remote host will go to the M204.

store tcpip proxy add host [

remotehost ipaddress

]

store tcpip proxy add host 192.147.242.3

4 Enable the IP gateway option on the M204 so that data packets will be sent from
