Firewall User Guide
Introduction
This chapter provides procedures for viewing or changing the configuration of a remote Firewall unit.
Remote configuration enables a PC at one site (local site) to dial a remote Firewall and change the
configuration of that remote unit. Remote configuration can be accomplished either directly through
the LAN or remotely using modems. To remotely configure a Firewall, a local PC needs to be
connected to a dial-up line and the Firewall software configured to call the remote Firewall. The
remote Firewall needs to have a modem connected to a dial-up line and the Command Port. Once
the connection to the remote unit is made, you can change the configuration as you see fit. Once the
configuration is changed, you can download the new configuration to the remote Firewall.
To configure the remote Firewall through the LAN, change the communication type to the IP based
Trivial File Transfer Protocol (known as TFTP) and change the configuration as you see fit. Refer to
the
LAN-Based Remote Configuration Procedure in this chapter to configure a remote Firewall.
Remote Configuration
Modem-based
1. At the remote site, disconnect the serial cable from the PC to the Command port jack on the Firewall.
2. At the remote site, connect a special cable (Remote Configuration Cable) between the Command
Port jack on the back panel of the Firewall and the (DB-25) RS232 connector on the modem. The
special cable is a serial cable with male connectors on both ends.
Connect the modem to your local telephone line.
Provide your telephone number to the person verifying your configuration.
3. At the main site, connect your local PC to a modem that is connected to a dial-up line.
4. Install the Firewall software on the local PC. When installed, click Start | Programs | Firewall
Version 3.00 | Configuration Port Setup, or double-click the Configuration Port Setup icon in the
Firewall Version 3.00 program group.
5. The Port Setup dialog box is displayed.
Verify that the Communication Type is set for COM Port and the Select Port field is set for the
COM port of your local PC.
In the Dial String field, enter the AT command for dialing (ATDT) plus the phone number of the
remote Firewall.
If your Modem Initialization String, Initialization Response, or Connect Response values are different
than the defaults in the dialog box, refer to your modem user documentation and change the default
values to match your modem.
