BQM alone will not trigger this. But if the router is receiving ping requests from more than one source then ICMP echo-requests may be ignored. e.g. BQM and our own line monitoring. This will look like packet loss on t he BQM graph.
A Ping Flood attack aims to overwhelm the targeted device’s ability to respond to the high number of requests or overload the network connection with bogus traffic.
The Ping flood attack may be mitigated by disabling the ICMP functionality of the targeted router. This is because an ICMP request requires some resources to process each request and to send a response. The request also requires bandwidth on both the incoming message and outgoing response. When the FRITZ!Box stops responding it is eliminating both the processing of the request and the Echo Reply.
you think i don't know that. lets move onto something i suggessted to zen. a way for me to see who was pinging(etc) my router since they supplied me with a route that didnt like that idea at all. "we will send you a router" ...............as long as you dont change the settings.
