Good Morning All

Just wondering how do I target this specific traffic, so I can add them to the list
without affecting my local network.

I have attached a screen shot showing same ip opened 2 connections to the router.

protocol UDP
on one SRC using port 80 ---> Hitting DNS and basically saturating my link.

At the moment, I'm just monitoring the traffic and if I see an unusual traffic I am manually blocking
it thereafter the same thing happens again with a different SRC.

Thanks guys in advance

There's traffic in both directions, do you have open resolver (= generally bad thing)? It would be good idea to fix that.

Thanks

I don't know why I didn't think about the simplest method as just blocking external traffic to the DNS.

Added the rules, hopefully that should fix it.

Thanks again

The default rules block WAN to Router traffic (including external DNS) and WAN to LAN traffic, what did you do to mess that up?
