Egress filtering is a method of restricting a computer network’s traffic for the purpose of enforcing security. Outgoing packets are monitored as they pass through a router or gateway, and if they violate any security policies, they are denied egress: they are not allowed to exit the network. In corporate networks that practice egress filtering, packets are usually restricted if they did not originate from a limited set of trusted internal servers....
