LAN
Network settings for the LAN network port may be assigned statically, or dynamically by
a DHCP server (Direct LAN). Alternatively you may choose to configure LAN port as a
bridge (Bridged LAN).
Direct LAN
To assign network settings statically, enter an IP Address and Netmask for the LAN
network port. If you are using the CyberGuard SG appliance in its default, network
address translation mode, (see Network address translation in the Advanced section of
this chapter), this will typically be part of a private IP range, such as 192.168.0.1 /
255.255.255.0. Ensure DHCP assigned is unchecked.
If you wish to have your CyberGuard SG appliance obtain its LAN network settings from
an active DHCP server on your local network, check DHCP assigned then Apply. Note
that anything in the IP Address and Netmask fields will be ignored.
You may also enter one or more DNS servers. Multiple servers may be entered
separated by commas.
