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.
This feature is for Advanced Administrators only!
Incorrect configuration may cause serious problems.
Firewall Rules
Incoming Rules |
These rules apply to incoming traffic. (Traffic means connections, not packets.)
- If you have not defined any rules, the list will contain only the default rule.
- The default rule will block all incoming traffic.
For each rule, the following data is shown:
- Name/Number - The default rule has the name "Default". Rules created using the Virtual Server feature will display "Virtual Server". Any other rules are numbered.
- Enable - Indicates if the rule is currently enabled. For rules you have created, you can Enable or Disable the rule by using the checkbox.
- Service Name - The Service (e.g. FTP) covered by this rule.
- Action - The action to be performed on this traffic. Since the default is "Block", most incoming rules will "Allow" the traffic.
- LAN Server IP address - The IP address of the PC on the LAN which will receive this traffic. This is sometimes called "Port Forwarding", because the port number (set by selecting te Service) determines which PC will get the traffic.
- WAN Users - The WAN IP addresses covered by thie rule.
- Log - Indicates whether or not traffic covered by this rule will be logged.
