3.6.1.2 IP Protocol Filters Fig. 55. IP protocol filters settings.
The protocol, source address, and destination address fields of a packet incoming from
the WLAN or Ethernet interface is inspected for filtering. In a rule, specify the
hex-decimal protocol number, source IP address range (Source IP Address AND
Source Subnet Mask), and destination IP address range (Destination IP Address AND
Destination Subnet Mask).
A source (destination) IP address range is determined by performing an AND operation
on the source (destination) IP address field and the source (destination) subnet mask
field. For example, if the source IP address field is 192.168.1.254 and the source subnet
mask field is 255.255.255.0, the resultant source IP address range is 192.168.0.0 to
192.168.0.255.
3.6.1.3 TCP/UDP Port Filters Fig. 56. TCP/UDP port filters settings.
The destination port field the TCP or UDP header of a packet incoming from the WLAN
or Ethernet interface is inspected for filtering. In a rule, specify the decimal Destination
Port, Protocol type (TCP/UDP), and the name of the higher-level protocol (Application
Name).
