Unlike
Internet
,
DMZ
or
COM1
ports, the
LAN
network port has only one configurable

To assign network settings statically, enter an
IP Address
and
Netmask
for the
LAN
network port. If you are using the SnapGear 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 SnapGear 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.
