What is this home RT-AC68u router trying to tell me? System log file seems to have maybe thousands of these lines at times the last few days 380.69_2 . The time stamp for what it is worth seems to coincide with the owners son getting home from school and firing up his tower of power loaded with Steam games and other stuff. (but not always). Thank you for any advice anyone can offer.

It’s just a load of old sockets getting binned.
Steam/online games often use a lot of connections, as do torrent downloads.
All this is are sockets which have been closed but are hanging around just in case they get re-used getting forcibly closed as there are so many of them the router has run out of space to track them.

Not THAT many connections.
The default config is pretty high.

He is either getting DDOS or part of a botnet.

The tower of power need a health visit, and needs to wear a condom going forward.
My bet is a sketchy "game hack/exploit" infected him

Thanks.

Something is blocking updates on his Windows 10 gaming machine once it got to Ver 1709 in December so its elevated my interest. Thinking it may be time to take advantage of Windows Fresh Start and redo the PC. 2 hours of investigation has not solved the problem so it may be best to blow it away.

My money is that ‘someone’ is torrenting stuff.

that i can investigate.

the second thread you have here is interesting though as the guy claims he did not see it until updating his firmware and when he goes back it vanishes. Kind of my case. never seen it before for whatever reason until getting on this one.
 
Network Tools - Netstat - Netstat-nat - by source IP

Unless he set his peer limit to infinity, I don't know how he is maxing the table. It's pretty big compared to older routers.

So I use this to see which device on the Lan has the most natted connections? would this be a way to short list possibilities?
