Seems they updated it to ports 1024 - 65535 which is only marginally better. Meaning someone at Nintendo put some thought into it and still decided that this is the best guidance they can give..

I had connection issues with the wiiu and pfsense. I remember coming across a support article to the same tune as this. Sent it to my room mate who is the most skilled network engineer i've known and i gotta say, i have never heard a laughter like that before. The mockery was thick.

Anyway, the actual issue is nat-port randomization in pfsense. Just set nat to preserve source port and you'll be good.

On a PC or smart device

Hold on, gonna configure my router settings from the smart fridge. Just have to watch this ad first

Equivalent of every software/system vendor saying their service account needs domain admin.

"just do it so we don't have to pay for customer support to do it"

Might as well put it in the dmz.

I wonder what the 1 to 9 was

I mean, at least it's not an any any rule...

Firewalls and NAT suck. Users have to go through strange procedures in their router's unpolished, bespoke interface just to be able to run a server. Imagine having a phone that can make calls but not receive them. The internet is broken.
