Spoofing is a process of translating the IP address of a given packet so that a firewall will believe the request came from a trusted source. Although the packet cannot be routed back to the initial source, there is potential for unnecessary network congestion and possible denial of service. WinRoute is capable of monitoring traffic to verify that packets arriving on an interface do not have a source address which is associated with a network of an opposing interface. In other words, such traffic (although possible) is never justified and should therefore be discarded.

The Anti-Spoofing function can be configured in the Anti-Spoofing folder in Configuration / Advanced Options.
