ProSafe Wireless-N VPN Firewall SRXN3205 Reference Manual • Enable DNS Proxy. Allows the firewall to handle DNS queries from the LAN. • Enable Stealth Mode. Prevents the firewall from responding to incoming requests for unsupported services. As you define your firewall rules, you can further refine the application according to the following criteria: • LAN Users. These settings determine which computers on your network are affected by this rule. Select the desired IP Address in this field. • WAN Users. These settings determine which Internet locations are covered by the rule, based on the IP address. - Any: The rule applies to all Internet IP address. - Single address: The rule applies to a single Internet IP address. - Address range: The rule is applied to a range of Internet IP addresses. • Destination Address. These settings determine the destination IP address for this rule which will be applicable to incoming traffic. This rule will be applied only when the destination IP address of the incoming packet matches the IP address of the WAN interface. Selecting ANY enables the rule for any LAN IP destination. • Services. You can specify the desired Services or applications to be covered by this rule. If the desired service or application does not appear in the list, you must define it using the Services menu (see "Adding Customized Services" on page 5-15). • Schedule. You can specify whether the rule is to be applied on the Schedule 1, Schedule 2, or Schedule 3 time schedule (see "Setting Schedules to Block or Allow Traffic" on page 5-17). See "Using Rules & Services to Block or Allow Traffic" on page 5-2 for the procedure on how to use this feature. Port Triggering Port triggering allows some applications to function correctly that would otherwise be partially blocked by the firewall. Using this feature requires that you know the port numbers used by the application. Once configured, port triggering operates as follows: • A PC makes an outgoing connection using a port number defined in the Port Triggering table. • This firewall records this connection, opens the additional INCOMING port or ports associated with this entry in the Port Triggering table, and associates them with the PC. 9-6 Firewall and Network Management v1.0, October 2008
