When the CyberGuard SG appliance is in bridged mode, it will not be performing NAT/masquerading. PCs will typically use an IP address on the network connected to the CyberGuard SG appliance’s Internet port as their gateway, rather than the CyberGuard SG appliance itself.

Failover Direct/Cable/ADSL Internet

Refer to the section entitled Internet Failover in this chapter.

COM/Modem

With a modem attached, the COM (serial) port can be configured as a primary Dialout Internet connection, to provide Dialin Access for remote users, or as a secondary Failover Dialout Internet connection that will be activated when your primary Internet connection becomes unavailable (e.g. ISP equipment or the telecommunications network may temporarily fail).

Physically connect modem device

Attach the modem serial cable to the CyberGuard SG appliance’s serial port (COM1).

Note

To connect to an ISDN line, the CyberGuard SG appliance requires an intermediate device called a Terminal Adapter (TA). A TA connects into your ISDN line and has either a serial or Ethernet port that is connected to your CyberGuard SG appliance. Do not plug an ISDN connection directly in to your CyberGuard SG appliance.

Dialout Internet
