I don't know whether it's appropriate to post this question here but I desperately need help.
I've been receiving ping requests from 18 different IP addresses so far. Some of them are local, some are from US and Russia. In half an hour, my router dropped 220 ping requests. And last night, my router logged that there's SYN Flooding attacks, TELNET requests, and SYN-FIN attack
It got me disconnected from the net quite a lot of times. So, are the ping requests a DoS attack or it's really THAT NORMAL to have so many ping in such a short amount of time. And also, any solutions will be greatly appreciated.
