Note: Inbound rules on the LAN WAN Rules screen take precedence over
inbound rules on the DMZ WAN Rules screen. When an inbound
packet matches an inbound rule on the LAN WAN Rules screen, the
packet is not matched against the inbound rules on the DMZ WAN
Rules screen.
To access the DMZ WAN Rules screen for IPv4 or to change existing IPv4 rules:
Select Security > Firewall > DMZ WAN Rules. In the upper right of the screen, the IPv4
radio button is selected by default. The DMZ WAN Rules screen displays the IPv4 settings.
(The following figure contains examples.)
Figure 69.

the rule, click one of the following table buttons:
•Up. Moves the rule up one position in the table rank.
•Down. Moves the rule down one position in the table rank.
•Edit. Allows you to make any changes to the definition of an existing rule. Depending on
your selection, one of the following screens displays:
-Edit DMZ WAN Outbound Service screen for IPv4 (identical to Figure 71 on
page 148)
-Edit DMZ WAN Inbound Service screen for IPv4 (identical to Figure 73 on page 151)
