Serial Port Configuration

This chapter describes how to configure the serial port options of your ProSafe Wireless 802.11g

Firewall/Print Server Model FWG114P v2. The FWG114P v2 serial port lets you share the

broadband connection of another FWG114P v2, share resources between two LANs, and take

advantage of the routing functions on the broadband (WAN), LAN, and serial network interfaces.

Note

: If you configure the serial port of the FWG114P v2 as the primary Internet connection, you

will not be able to configure the other serial port options. For instructions on configuring the serial

port as the primary Internet connection, please see

“How to Configure the Serial Port as the

Primary Internet Connection“ on page 3-15

.

The FWG114P v2 provides these serial port configuration options:

•

Modem

Use this option to configure the serial modem settings for any of the features below.

•

Auto-Rollover

Use this option to provide a backup connection for your broadband service. If the broadband

service you configured in the Basic Settings menu fails, the FWG114P v2 will automatically

connect to the Internet through the serial port. However, you will then be accessing the

Internet at a slower speed than you would through your broadband service.

•

Dial-in

Dial-in lets a single remote computer connect to the FWG114P v2 through the serial port to

gain access to LAN resources or a remote access server.

•

LAN-to-LAN

LAN-to-LAN enables direct communications between two FWG114P v2 wireless firewall/

print servers to:

—

Share resources on the two LANs.

—

Let users on one FWG114P v2 share the Internet connection of the other FWG114P v2.

—

Let users on one FWG114P v2 connect to the Internet through the second FWG114P v2 in

case the broadband connection of the first FWG114P v2 fails.

The procedures for these configuration options are presented below.
