DoS Attacks, RST/ACK Scan. Disconnecting from old Computer game when this happens, (Ultima Online)
I am at my wits' end, trying to figure out how to stay connected to this game when this happens. Nothing else is affected, not the Cable TV or other programs on the same computer or another computer....
It looks like the game I am playing uses port 80, as does a lot of the traffic from the false flags. Therefore, when it labels this traffic as nefarious, the router perhaps momentarily stops the flow on port 80, causing me to disconnect from my old game that can not handle this action. The only thing I can think of now is replacing this router with something that does not throw false flags, like John Elway throws touchdowns. So disappointed in this router.
Add the device to Traffic Controller and allow port 80 for it and see if that works better. You could also try setting NAT to Open in WAN Settings which relaxes the firewall a little - start with this one first.
Done. Monitoring over the next few days....
To be clear, in the hopes of isolating the cause, I only opened the NAT.
Worked all day until the following from the router log file, All my accounts disconnected when this happened. These IP's and the DoS attack is the same one that always disconnects me.

Also, the below happened during the day, and I did not disconnect: (This repeated over 900 times, but I had to cut it because of forum rules.)
