LAN
Unlike Internet, DMZ or COM1 ports, the LAN network port has only one configurable
function, to connect to your local area network. Network settings for the LAN network
port may be assigned statically, or dynamically by a DHCP server. Select Edit current
settings to continue.
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.
