Firewall Rules

For normal operation and LAN protection, it is not necessary to use this screen.

The Firewall will always block DoS (Denial of Service) attacks. A DoS attack does not attempt to steal data or damage your PCs, but overloads your Internet connection so you can not use it - the service is unavailable.

As well, you can use this screen to create Firewall rules to block or allow specific traffic. But Incorrect configuration may cause serious problems.

This feature is for advanced administrators only!

Firewall Rules Screen

Click the Firewall Rules option on the Security menu to see a screen like the following exam- ple. This example contains two (2) rules for outgoing traffic.

Since the default rule for outgoing (LAN => WAN) traffic is "Allow", having an "Allow" rule for LAN => WAN only makes sense in combination with another rule.

For example, the screen below shows a rule blocking all traffic to a MSN Game Server, followed by another rule allowing access by a specific PC.
