LAN WAN Outbound Rules and DMZ WAN Outbound Rules (Service Blocking)
You can control specific outbound traffic (from LAN to WAN and from the DMZ to WAN). The
LAN WAN Rules screen and the DMZ WAN Rules screen list all existing rules for outbound
traffic. If you have not defined any rules, only the default rule is listed. The default rule allows
all outgoing traffic. Any outbound rule that you create restricts outgoing traffic and therefore
decreases the traffic load on the WAN side.
WARNING!
This feature is for advanced administrators. Incorrect
configuration might cause serious problems.
Each rule lets you specify the desired action for the connections that are covered by the rule:
• BLOCK always
• BLOCK by schedule, otherwise allow
• ALLOW always
• ALLOW by schedule, otherwise block
The following section summarizes the various criteria that you can apply to outbound rules in
order to reduce traffic. For more information about outbound rules, see
(Service Blocking) on page 109. For detailed procedures on how to configure outbound rules,
see Set LAN WAN Rules
When you define outbound firewall rules, you can further refine their application according to
the following criteria:
• Services. You can specify the services or applications, or groups of services or
applications to be covered by an outbound rule. If the desired service or application does
not display in the list, you need to define it using the Services screen (see
Rules on page 109 and
• LAN users. You can specify which computers on your network are affected by an
outbound rule. There are several options:
- Any. The rule applies to all PCs and devices on your LAN.
- Single address. The rule applies to the address of a particular PC.
- Address range. The rule applies to a range of addresses.
- Groups. The rule applies to a group of PCs. (You can configure groups for LAN WAN
outbound rules but not for DMZ WAN outbound rules.) The Known PCs and Devices
table is an automatically maintained list of all known PCs and network devices and is
generally referred to as the network database, which is described in
