rebooted router and got different ip address but still getting [Service blocked: ICMP_echo_req] from source

infact so far today have had 169 of them

You might want to run an anti-virus scan on your computer(s).  You might have some malware that is reporting your IP address, inducing the multiple sites to probe your router for weaknesses.  Some of those IP addresses belong to less than reputable regions of the world.

Or maybe someone is DDoS-ing you.

[goatty2]

I have ran the virus checker, malwarebites and spybot nothing showed up.

normally says Dos attack when it happens had that couple of weeks ago but not a proper one as only 3 of them

[TheEther]

Well, I guess there's not much else to do other than insure that Respond to Ping on Internet Port is unchecked in WAN Setup on the D6400.  You want to make your D6400 as invisible to hackers as possible.

did another reboot at 11am IP address changed again and so far not had any service blocked

so hope it cured
