• If you are defining a static address, clear the checkbox and continue with the next step. You must
define the IP address and Subnet Mask.
To assign network settings statically, enter an address in the IP Address field. If you are using the UTM
6
Firewall appliance in its default network address translation mode, this is typically part of a private IP
address range, such as 192.168.0.1 / 255.255.255.0.
Enter the subnet mask you want to use for this port in the Subnet Mask field.
7
Range: 0-32; can also be in the form 255.255.255.0
If required, enter the IP address of the default Gateway out which to send outgoing traffic on this
8
connection. If the default gateway is via the DMZ, define this setting. For LAN connections, a default
gateway is not generally necessary.
[Conditional, if not using DHCP. Optional if using DHCP.] Enter one or more DNS servers the appliance
9
uses for DNS resolution in the DNS Servers field. To enter multiple servers, separate each IP address
with a comma. Any DNS server addresses allocated by the DHCP server take precedence over entries in
this field.
Select a classification from the Firewall Class list. The Firewall class setting controls the basic allow/deny
10
policy for this interface. Allowed network traffic is accepted, denied network traffic is dropped. Dropped
means network traffic is denied silently; no response such as "connection refused" is sent back to the
originator of the traffic.
The policy associated with each firewall class is detailed in
assigned a firewall class of LAN by default.
