how to coop?

title when friend tries to join gets nat type strict

[Cracky McWestside]

If your internet router is in strict NAT it prevents you from playing in multiplayer.

You'll have to switch to a different network settings on your side, if possible. If this doesn't work, you'll have to check with your ISP.

The two following ports have to be open:

TCP: 11700-11710
UDP: 48800-49000

To do so, please do the following:

Search for Windows Defender Firewall with Advanced Security
Open Inbound Rules and click on "New Rule..." on right side of the window.
Make rule SR1: Port > TCP > Specific local ports 11700-11710 > Allow the connection
Make rule SR2: Port > UDP > Specific local ports 48800-49000 > Allow the connection
Open Outbound Rules and do the previous two steps with opening ports

Already try that... Did not work... Me and my brother did all the port opening and still can't play coop...

Then it is most likely an issue with your ISP.

You posted these ports a few times now if I remember correctly. Doesn't the Steam version have more ports? That's at least what I can find online.

SnowRunner - Steam
TCP: 11700-11710,27015-27030,27036-27037
UDP: 4380,27000-27031,27036,48800-49000

The NAT detection in the game is currently faulty. If the port forwardings don't work and the game is not blocked by your firewall, then there is nothing you can do about it. It is not a problem with the ISP, it's just the detection that screws up.

Are there any plans to fix this, really annoying bug

[Flash]

The bug as been known for over a year and hasn't been fixed. So the chances are slim.

[wuki1989(DE)]

That is no bug .... it's a problem with your or with your friens internet connection /provider/router settings /networ settings etc

I had to use a VPN (testet phantom vpn ... was bad....ended with Nord VPN-> works great-> 2 years Nord VPN for now )

So if your NAT is strict or your connection has problems with some protocols etc and you can't fix it on your side (because it's a problem at your provider like in my case) you have to make a choice :

change your provider to another one and hope it's working
use a VPN like I do and have no problems to connect ever again with any program
(if it's not possible in 1st try i simply switch vpn protocole)
I can just speak for myself .... Nord VPN is great if you're willing to spend the money for it ....
In my case totally worth it

You can use another VPN provider .... but I can't say much about the others .... surfshark is another provider with mostly good ratings.... but there are some other good vpn services with good servers out there ....
Just try it out ... most of them have a cash back if you're not satisfied with their product

How is it not a bug with the game? over 200 steam games - origin games uplay ect..... never heard had or seen this issue before even when playing old modded games like soulstorm or FAF it sort of is a game bug

The reason it is not a bug, is that the fix isn't found in the game, but rather somewhere else.
That being a router setup done wrong, a firewall issue or an ISP issue.

The game works perfectly, provided everything else is working correctly.

While I cannot prove it, I still beg to differ. Yes, there are probably a lot of router settings and other stuff to blame for this issue. However, since release of Phase 4 this and several other issues suddenly appeared, which seemed to never be an issue before according to the official forum. I tend to believe there is a mixture of both, people with 'wrong settings' and an issue with the game itself. Without an official statement we don't certainly know, what is up with this issue.

Dosent Matter just tried nord Vpn, didnt work just refunded the game might try later if the game devs can figure out how every other game runs multiplayer

[Flash]

In some cases, it could very well be a configuration problem. The fact still stands though, that this is the only game for many that has these kinds of issues. All other games run fine.

I am pretty certain that it might just be a problem with how the game tries to determine the NAT-type. This would be easily diagnosable if the game allowed us to turn off said check and see if we can get Multiplayer running. If the issue stems from where I think it does, then disabling the NAT-type check (maybe with a run-option at gamestart) would allow alot of people to play until the check has been reworked to return reliable information about the network-setup.
