Set DMZ WAN Rules
The firewall rules for traffic between the DMZ and the Internet are configured on the DMZ
WAN Rules screen. The default outbound policy is to block all traffic from and to the Internet.
You can then apply firewall rules to allow specific types of traffic either going out from the
DMZ to the Internet (outbound) or coming in from the Internet to the DMZ (inbound).
There is no drop-down list that lets you set the default outbound policy as there is on the LAN
WAN Rules screen. You can change the default outbound policy by enabling all outbound
traffic and then blocking only specific services from passing through the UTM. You do so by
adding outbound services rules (see DMZ WAN Outbound Service Rules on page 135).
To access the DMZ WAN Rules screen, select Network Security > Firewall > DMZ WAN
Rules. The DMZ WAN Rules screen displays. (The following figure shows some rules as an
example.)
Figure 68.

To make changes to an existing outbound or inbound service rule:
In the Action column to the right of to the rule, click one of the following table buttons:
• Edit. Allows you to make any changes to the definition of an existing rule. Depending on
your selection, either the Edit DMZ WAN Outbound Service screen (identical to Figure 69
on page 135) or the Edit DMZ WAN Inbound Service screen (identical to Figure 70 on
page 136) displays, containing the data for the selected rule.
• Up. Moves the rule up one position in the table rank.
• Down. Moves the rule down one position in the table rank.
