Thanks again Fraser. I will give that a try. Just wondering what settings my AX11000 should handle versus what the R3 will be doing. For example: turning off QOS on the main router because R3 will be doing that for me, etc. I don't want to have wrong settings on either router that will detract from what I'm expecting out of the R3. I'm not sure if iPv6 needs to be off on one or the other. iPv6, Allow ping, Portscan and Syn Flood are 3 things turned off in the video I reference above. I'm no networking genius. Just trying to learn but it is MW3 that put me on this path!
