The setting procedure written on the page is as follows.

・ Select 'Manual'
-Select 'IP address' and delete the existing IP address while holding down the B button. (The default is zero.)
-Enter the IP address you found on your network device, but add '20' to the last section of the number and select 'OK'. (If '192.168.2.5' is displayed in the IP address part, change it to '192.168.2.25'.)
-Select 'Subnet Mask' and delete the existing subnet mask while holding down the B button.

Of the series of setting methods, the description in the setting method on the router side is strange: 'Enter the start port and end port to be forwarded within the range of the port. In the case of Nintendo Switch, the port is' 1 to 65535 '.' Hacker News users point out.
'1 to 65535' refers to all ports, but ports 1 to 1023 are called well-known ports and are used for basic services. In addition, since the ports used as dynamic IP addresses and private ports are 49152 to 65535, Nintendo's description as if all ports including other ports can be used is 'a strange explanation. 'Hacker News users point out.
From users, 'I hope the person who wrote this support page wasn't involved in the firewall settings.' 'Needless to say, Nintendo is too ignorant ...' 'To disable UPnP on routers in the PS3 era.' I had to do the same thing. '
In addition to this, DHCP has already assigned the statement 'Enter the IP address found on the network device, but add' 20 'to the last section of the number and select' OK '.' It should not be recommended as it may overlap with the IP address assigned in the future.
There is no page about port forwarding on Nintendo official support in Japan.
