Definition
Specifies network addresses to enable the appliance to communicate with your
network.
You can specify multiple IP addresses for the appliance's ports. If the appliance is in
Transparent Bridge mode, the IP addresses are combined into one list for both ports.
In the other modes, click Network Interface 1 or Network Interface 2 to work
on each of the two lists.
The IP address at the top of a list is the primary address. Any IP addresses below it
are "aliases."
Specifies network mask, for example: 255.255.255.0.
Definition
Specifies the DNS servers. The first server in the list must be your fastest or most
reliable server. If the first server cannot resolve the request, the appliance contacts
the second server. If no servers in the list can resolve the request, the appliance
forwards the request to the DNS root name servers on the Internet.
If your firewall prevents DNS lookup (typically on port 53), specify the IP address of
a local device that provides name resolution.
Displays the network address of a routing device.
Displays the network subnet mask such as 255.255.255.0.
Specifies the IP addresses of other gateways (typically firewall or routers) through
which the appliance will communicate with the network.
The Basic Settings page specified the default gateway.
Displays a number used by routing software. Default value is 0.0.
Dynamic routing allows your network devices, including the appliance, to listen for the
routing information that routers broadcast on your network. The devices can use that
information to configure their own routing information.
NOTE: The appliance supports only the Routing Information Protocol (RIP) and Open
Shortest Path First (OSPF) routing protocols.
