Use ports and/or IP addresses to define the type(s) of traffic attached to this rule. Leaving any field blank will match all values; all fields are optional.
Source Port(s) and/or Destination Port(s): Enter a port number between 1 and 65535. To enter a single port number, input the number into the left box. To enter a
range of ports, fill in both boxes separated by the colon. For example "80:90" would represent all ports between 80 and 90 including 80 and 90 themselves.
Source IP Address, Source Netmask, Destination IP Address, and Destination Netmask: Specify an IP address or range of IP addresses by combining an IP
address with a netmask for either "source" or "destination" (or both). Source vs. destination is defined by traffic flow. Leave these blank to include all IP addresses (such as if
your rule is defined by a particular port instead).
EXAMPLE: If you want to associate this rule with your guest LAN, you could input the IP address and netmask for the guest LAN here
(leaving the last slot "0" to allow for any user attached to the guest network):
Source IP Address: 192.168.10.0
Source Netmask: 255.255.255.0
DSCP (DiffServ): Differentiated Services Code Point (DSCP) is the successor to TOS (Type of Service). Use this field to select traffic based on the DSCP header in each IP
packet. This field is sometimes set by latency sensitive equipment such as VoIP phones.
This setting is optional. For more information see the
DSCP Negate: When checked this rule will match on any packet that does not match the DSCP field.
