Filter basics

In the source or destination IP address fields, the IP address that is entered must be the network address
of the subnet. A host address can be entered, but the applied subnet mask must be 32 bits
(255.255.255.255).
Netopia Embedded Software Version 7.7.4 has the ability to compare source and destination TCP or UDP
ports. These options are as follows:
No Compare
Not Equal To
Less Than
Less Than or Equal
Equal
Greater Than or Equal
Greater Than
