4. Dialin Setup
CyberGuard SG appliance enables remote and secure access to your office network.
This chapter shows how to set up the dialin features.
Your CyberGuard SG appliance can be configured to receive dialin calls from remote
users/sites. Remote users are individual users (e.g. telecommuters) who connect directly
from their client workstations to dial into modems connected to the serial ports on the
CyberGuard SG appliance. Remote site dialin connections can be LAN-to-LAN
connections, where a router at a remote site establishes a dialin link using a modem
connected to the CyberGuard SG appliance.
The CyberGuard SG appliance’s dialin facility establishes a PPP connection to the
remote user or site. Dialin requests are authenticated by usernames and passwords
verified by the CyberGuard SG appliance. Once authenticated, remote users and sites
are connected and have the same access to the LAN resources as a local user.
To configure the CyberGuard SG appliance for a dialin connection:
1. Attach an external modem to the appropriate CyberGuard SG appliance serial port
(COM1).
2. Enable and configure the CyberGuard SG appliance serial (COM) port for dialin.
3. Set up and configure user dialin accounts for each person or site requiring dialin
access.
You can also apply filtering to dialin connections, as detailed in the chapter entitled
Firewall.
