DoS ICMP Flood

Hello All,

Over the past few weeks, I have been seeing Dos Attack ICMP Flood from what looks like an ipv6 address.  It causes no disruptions in my internet connections from what I've seen OTHER than in gaming.  I lose connection from games on the Xbox platform.  My Xbox connection drops at the same times as the ICMP floods.  This is happening approximately every hour.  I read a few posts on here but couldn't find a solid answer as most did not show the same log entries as what I have. Below is a sample.  Does anyone know how to stop these?  I have ipv6 enabled, Upnp enabled, dos protection on, etc.  Thanks in advance for your help!
