– Address Range: A range of IP addresses on the LAN will be affected by the rule.
– Group: Computers that are part of the Group defined in the Network Database will be
affected by the rule (groups are defined under the Network Configuration menu, LAN
Groups page on the Edit Group Names tab).
WAN Users: Specifies whether all Internet addresses or specific IP addresses are included in the
rule.
– Any: All IP addresses on the Internet are included in the rule.
– Single Address: A single Internet IP address that is affected by the rule.
– Address Range: A range of IP addresses that are affected by the rule.
• Destination: The WAN IP address that will map to the incoming server. It can either be the
address of the ADSL or WAN Ethernet port* or another WAN IP address.
Note: This field is only enabled when under NAT mode since the router needs to
map traffic coming from a particular WAN port to a LAN machine.
• Priority: The priority assigned to IP packets of this service. The priorities are defined by
"Type of Service (TOS) in the Internet Protocol Suite" standards, RFC 1349. The router marks
the Type Of Service (TOS) field as defined below:
– Normal-Service: No special priority given to the traffic. The IP packets for services with
this priority are marked with a TOS value of 0.
– Minimize-Cost: Used when data must be transferred over a link that has a lower "cost".
The IP packets for services with this priority are marked with a TOS value of 1.
– Maximize-Reliability: Used when data needs to travel to the destination over a reliable
link and with little or no retransmission. The IP packets for services with this priority are
marked with a TOS value of 2.
– Maximize-Throughput: Used when the volume of data transferred during an interval is
important even if the latency over the link is high. The IP packets for services with this
priority are marked with a TOS value of 4.
– Minimize-Delay: Used when the time required (latency) for the packet to reach the
destination must be low. The IP packets for services with this priority are marked with a
TOS value of 8.
• Log: Specifies whether the packets for this rule should be logged or not. To log details for all
packets that match this rule, select Always. Select Never to disable logging.
