MyBook Live is a source of ping flood attack

So I’ve been checking my router (D-Link Dir-300) settings and noticed this in log:

“PING-FLOODING flooding attack from LAN (ip: detected.” it seems to happen all the time.

IP is MyBook :

MyBookLive 00:90:A9:BA:CE:B6 21 hr(s) 29 min(s) 40 sec(s)

Shoud I be worried?

Hello, welcome to the community.

You might want to take a look at your firewall settings at your firewall settings at your router, and this attack can remove stop giving you access to the internet. If the firewall settings are ok, I would turn off the remote access and see if the attack stop.
