Serial Port Configuration
This chapter describes how to configure the serial port options of your FVS328 ProSafe VPN
Firewall with Dial Back-up. The FVS328 serial port lets you share the broadband connection of
another FVS328, 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 FVS328 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
“Configuring a Serial Port as the Primary Internet
Connection“ on page 3-9
.
The FVS328 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 FVS328 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 FVS328 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 FVS328 firewalls to:
—
Share resources on the two LANs.
—
Let users on one FVS328 share the Internet connection of the other FVS328.
—
Let users on one FVS328 connect to the Internet through the second FVS328 in case the
broadband connection of the first FVS328 fails.
The procedures for these configuration options are presented below.
