Allows the use of subnet masking to define the included/excluded host addresses.
The IP Subnet Mask filter allows you to specify a range of IP addresses to include or exclude based on mask matching.
Either the 'Include' or 'Exclude' fields can be left blank, but not both.
If the 'Include' fields is left blank the filter works in exclusion mode. If the IP address falls in the range of the 'Exclude' values, the result is true.
The IP address specified is logically AND'd with the specified Mask and then compared with the message host IP address. If the two addresses are on the same "subnet" then the result is true.
The filter above reads as:
If the IP address falls within the range of 220.127.116.11 to 18.104.22.168 then the result will be true.
This is an example of an exclusion filter:
If the IP address does NOT fall within the range of 22.214.171.124 to 126.96.36.199 then the result will be true.
