Domain Based Packet Filtering

Domain based packet filtering is a simple filter allowing to restrict user communication based on the source/destination domain name. This is especially useful if we want to limit user communication within a single - own domain only or a list of domains.

A company might not wish to allow employers to chat during work hours with anybody in the world. A company may also have a few different domains used by different branches or departments. An administrator may restrict communication to a list of domains.
