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. Any outbound rule that you create restricts outgoing traffic and therefore decreases
the traffic load on the WAN side.
On the LAN WAN screen, if you have not defined any rules, only the def
ault rule is listed. The
default LAN WAN outbound rule allows all outgoing traffic.
WARNING:
Incorrect configuration of outbound firewall rules can cause
serious connection 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
• AL
LOW always
• ALL
OW by schedule, otherwise block
The following section summarizes the various criteria th
at you can apply to outbound rules in
order to reduce traffic. For more information about outbound rules, see Outbound Rules
(Service Blocking) on
page 130. For detailed procedures about how to configure outbound
rules, see Configure LAN WAN Rules on
page 138 and Configure DMZ WAN Rules on
page 145.
When you define outbound firewall rules, you can further refine their application according to
t
he following criteria:
• Servi
ces. You can specify the 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 Outbound Rules (Service Blocking) on
page 130 and Add
Customized Services on p
age 172).
• L
AN users (or DMZ users). You can specify which computers on your network are
affected by an outbound rule. There are several options:
- Any. Th
e rule applies to all computers and devices on your LAN.
