Interface aliases
Interface aliases allow the CyberGuard SG appliance to respond to multiple IP
addresses on its LAN, Internet and DMZ ports. For Internet and DMZ aliased ports, you
must also setup appropriate Packet Filtering and/or Port forwarding rules to allow
traffic on these ports to be passed onto the local network. See the chapter entitled
Firewall for details.
