Our network segment that we are connected to has traffic associated with one subnet. I want to setup a BPF filter on the sensor so that only traffic associated with the subnet is processed. Can we do this and what is the syntax that should be used?

If you want to filter traffic at a sensor level you should use the following syntax in the sensor settings page


Just be sure to set it for traffic monitoring and IDS

From what I can see, this syntax net does not work.

This problem can be remedied with the filter
