ICMP Flood detected

[_AtaLoss]

I have BT Broadband, a static IP and keep getting a warning from my 2 Wire Router

by e-mail that I have and ICMP flood detected. My concern is that someone is trying to

hack into my router (BT HGV2700) and network.  Any suggestions would be greatly appreciated.

Thanks

You could enable Block Ping in Settings> Firewall> Advanced Configuration, this should drop any ICMP packets hitting the router.

Thank you for your suggestion A Hill.   I've made the change and I'm no longer receiving firewall alerts. However each of the 3 browsers I use is taking an age to load pages so I was wondering whether this means some packets of data maybe lost?  If so this route may not work as I use real time financial data for analysis and each change in price is important.  Could you possibly explain what disabling Ping achieves?  Thank you.

blocking ping, prevents others from recieving an answer from your router when they ping it.

if someone were to continually ping your router, it would become so busy that normal internet traffic would become impossibly slow. by not reponding to ping the offending pinger would just move on to the next victim.

some isps, used to require that ping remain on, so they could manage ip addresses and network load, based on wether or not they got a response to ping, they would disconnect any non responding connections, to release the ip address for other users.

if you are still having problems, i would suggest releasing and renewing the ip address you have now, and see if that helps.
