That's not portforwarding, that's moving to the DMZ...

As a network engineer, this made me audibly sigh.

Solid advice, redirect all incoming UDP traffic to your Switch, and your Switch alone...

Just curious, what if you have another layer of NAT, or your router is out of your control (and no UPnP)?

You just can't play networked games with Switch, or what?

Apparently you only _need_ to forward 45000~65535: https://www.reddit.com/r/NintendoSwitch/comments/6qjhjy/i_ha...

I went through this when setting up the switch to talk to someone behind heavy NAT over the holidays. 45000+ worked for me.

....which makes this even more ridiculous if it never uses them.

Just a quick advice, as I struggled with this as my daughter complained that she could not join network games in Animal Crossing because she had only “NAT Type D”.

Forwarding all these ports was the recommended solution in Nintendo’s docs. However, it did nothing to resolve this problem. What helped was to ensure not to modify source ports in the NAT setup (“static-port” in pf).

What's the reason not to open all ports btw? Outing myself as naive by asking

What, they can't use UPnP like a good citizen?

I cant believe a company this size could suggest such a thing, so has anyone tried doing this and then monitored what happens?

Is the Switch able to do other stuff which is not reported or mentioned anywhere?

PlayStation is pretty bad too, they want 80, 443 (and 1935, 3074, 3478-3479), if you don't you can get all sorts of really annoying problems joining games, delays joining voice chats etc....

If they need all your incoming traffic they should probably have called it a "router" not a "switch".

Darn, I hope this isn't the solution to the problem I have where my switch won't join other worlds on minecraft.

My s/o and her sister (CS student) regularly play Animal Crossing over the Internet. I (and the SIL) wanted to curse Nintendo to hell and back for requiring users to essentially put their Switches available to the wide Internet (meaning, as long as the Switch is powered on, any RCE exploit on the Switch turns it into a full, unrestricted gateway into my home network!) simply because Nintendo doesn't want to follow basic Internet standards like UPnP or, heaven forbid, provide STUN/TURN proxies paid for by the Nintendo Online subscription.

Hell it took years for them to implement Bluetooth audio on the Switch, and that's output-only, no microphone. What stuff is their software division smoking?

What is this needed for? I never set up any port forwarding and don't remember having any issues with network connectivity. But then again I don't play that much online.

It's pretty good advice, if you're Nintendo and spending a fortune trying to provide support advice to people with crappy router config/connections. Yes it's entirely likely to cause other problems - but probably going to get that switch working.

Other problems will go to other vendors - and if their advice stops your switch from working, that's on them.

This whole article is... optimistic.

> 4. Enter the IP address you found on the network device, but add 20 to the last section of digits, and then select OK.

> As an example, if your computer's IP address displays as 192.168.2.5, enter 192.168.2.25 on the Nintendo Switch.

Hope you don't have more than 20 devices on your network (after your PC), and that they're not configured to be close to 255 there...
