Abstract
An internal network (,) is protected from being overloaded by an excessive number of data packets that originate from a source in an external network (,). In a preferred embodiment, data packet gate (,) receives each incoming data packet and determines whether it came from a trusted source. If it was not from a trusted source, and the number of data packets received recently from the same source exceeds a threshold, then data packets from that source are rejected. Preferably, when incoming data packets from all non-trusted sources exceed another threshold, additional data packets from all non-trusted sources are rejected.
