Using Rules Table 33: Firewall Rule Types Rule Description Allow and Forward This rule type enables you to do the following: • Permit incoming access from the Internet to a specific service in your internal network. • Forward all such connections to a specific computer in your network. • Redirect the specified connections to a specific port. This option is called Port Address Translation (PAT). • Assign traffic to a QoS class. If Traffic Shaper is enabled for incoming traffic, then Traffic Shaper will handle relevant connections as specified in the bandwidth policy for the selected QoS class. For example, if Traffic Shaper is enabled for incoming traffic, and you create an Allow and Forward rule associating all incoming Web traffic with the Urgent QoS class, then Traffic Shaper will handle incoming Web traffic as specified in the bandwidth policy for the Urgent class. For information on Traffic Shaper and QoS classes, see Using Traffic Shaper on page 151. Creating an Allow and Forward rule is equivalent to defining a server in the Servers page. Note: You must use this type of rule to allow incoming connections if your network uses Hide NAT. Note: You cannot specify two Allow and Forward rules that forward the same service to two different destinations. Chapter 9: Setting Your Security Policy 211
