Trying to fix my Nintendo Switch NAT Type being D. Tried everything, need help.

Hi Facepunch, I don't usually ask for help on here but I'm at my wit's end at this point. My Switch NAT Type is D which basically means I can't fucking connect to anybody when trying to play Smash online. I've gone through a lot of shit trying to improve it but nothing is working.

I've tried Port Forwarding, that DMZ shit, everything Nintendo Support recommended. So please, for the love of god, does anybody know what satanic ritual I need to perform to play the damn game I payed for online?

if you're D, you're probably already being NAT'd at ISP level

is your external IP in one of these ranges?

yeah local ip is in the bottom range

[lordcrypto]

local IP or your external IP

local IP being in that range isn't an issue, your external IP being in that range is

just google "whats my IP"

[That Sprite]

oh my b. External IP is not in those ranges

Can you post your IP's just so we have a visual record of what you're seeing.

[That Sprite]

Are you sure posting that on a public forum is a good idea?

What IP is your Switch getting? Is it in that 10.168.x.x range?

What are your DHCP settings? Is your router ISP provided?

[lordcrypto]

it looks like parknet might be using carrier grade NAT

in that case there's nothing that can be done

[That Sprite]

Switch gets 192.168.x.xxx

How do I check my DHCP settings?

[lordcrypto]

yeah i'm gonna guess parknet has more than ~6192 customers

VPN?

[lordcrypto]

you'd have to set up another router in front of the already funky ass router to do the VPN, so possibly but it would be a mess

[Scratch]

Is that still necessary if the VPN is configured only on the console?

[lordcrypto]

didn't think there was VPN capability on switch

[Scratch]

It's got some basic proxy support, used it once to try packet sniffing (didn't work out due to ssl).

Only offers an IP, Port, and auth options

Unsure if desktop windows can do it but with a machine running linux you could do some magic (can't recall atm) and configure the switch to use it as a default gateway.
