ProSafe Wireless-N 8-Port Gigabit VPN Firewall FVS318N

Features That Reduce Traffic

You can adjust the following features of the wireless VPN firewall in such a way that the traffic load on the WAN side decreases:

•LAN WAN outbound rules (also referred to as service blocking)

•DMZ WAN outbound rules (also referred to as service blocking)

•Content filtering

•Source MAC filtering

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 default 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

•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 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 the following criteria:

•Services. 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 page 172).

•LAN users (or DMZ 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 computers and devices on your LAN.
