the problem with that is Nintendo switch different games use different ports and Nintendo suggest opening ports 1 - 65535 (https://en-americas-support.nintendo.com/app/answers/detail/a_id/22272/~/how-to-set-up-a-routers-port-forwarding-for-a-nintendo-switch-console) which is a huge security risk. I tried adding ports 1 - 65535 to the QoS but no dice. I have even tried different games tetris 99, poken tournament DX, splatoon 2, and nothing comes up.
