• 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 their 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 selected WAN interface

the respective WAN interface governed by this rule.

three different schedules (for example, schedule 1, schedule 2, and schedule 3) for when a rule
is to be applied. Once a schedule is configured, it affects all rules that use this schedule. You
specify the days of the week and time of day for each schedule. (See

Port Triggering
Port triggering allows some applications to function correctly that would otherwise be partially
blocked by the VPN 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.
• The VPN 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.
