5.3 Firewall Rule
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 example. 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.
