ProSafe Dual WAN Gigabit Firewall with SSL & IPsec VPN FVS336G Reference Manual Table 4-1. Outbound Rules (continued) Item WAN Users QoS Priority Log Description These settings determine which Internet locations are covered by the rule, based on their IP address. Select the desired option: • Any - All Internet IP address are covered by this rule. • Single address - Enter the required address in the start field. • Address range - If this option is selected, you must enter the start and end fields. This setting determines the priority of a service which, in turn, determines the quality of that service for the traffic passing through the firewall. By default, the priority shown is that of the selected service. The user can change it accordingly. If the user does not make a selection (leaves it as Normal-Service), then the native priority of the service will be applied to the policy. See "Setting Quality of Service (QoS) Priorities" on page 4-17. This determines whether packets covered by this rule are logged. Select the desired action: • Always - always log traffic considered by this rule, whether it matches or not. This is useful when debugging your rules. • Never - never log traffic considered by this rule, whether it matches or not. Inbound Rules (Port Forwarding) When the FVS336G uses Network Address Translation (NAT), your network presents only one IP address to the Internet and outside users cannot directly address any of your local computers. However, by defining an inbound rule you can make a local server (for example, a Web server or game server) visible and available to the Internet. The rule tells the firewall to direct inbound traffic for a particular service to one local server based on the destination port number. This is also known as port forwarding. Whether or not DHCP is enabled, how the PCs will access the server's LAN address impacts the Inbound Rules. For example: • If your external IP address is assigned dynamically by your ISP (DHCP enabled), the IP address may change periodically as the DHCP lease expires. Consider using Dyamic DNS (under Network Configuration) so that external users can always find your network (see "Configuring Dynamic DNS (Optional)" on page 2-18. • If the IP address of the local server PC is assigned by DHCP, it may change when the PC is rebooted. To avoid this, use the Reserved IP address feature in the LAN Groups menu (under Network Configuration) to keep the PC's IP address constant (see "Configuring DHCP Address Reservation" on page 3-8. 4-4 Firewall Protection and Content Filtering v1.0, October 2007
