[Overloader6]

So im running the viewer on linux and after clicking "connect" i get no change in the ui at all. The console logs this:

Is your firewall allowing outgoing and incoming udp packets for ntrviewer-hr?

Otherwise for troubleshooting there are a few things to try:

• Disable Reliable Stream (setting it to off),
• Try snickerstream instead, to make sure the problem isn't with ntr-hr

Is your firewall allowing outgoing and incoming udp packets for ntrviewer-hr?

I explicitely allowed udp port 8001 with iptables

• Disable Reliable Stream (setting it to off),

I tried that, didnt change anything

• Try snickerstream instead, to make sure the problem isn't with ntr-hr

I couldnt try it. Its a windows software and im on linux. trying to start it with wine made it crash

The log shows that the TCP connection is successful between 3DS and your Linux system, which is why it's likely an issue with firewall settings.

Specifically:

• 3DS port 8000 to viewer port 8001 (incoming) UDP need to be allowed for non-Reliable Stream.
• In addition viewer port 8001 to 3DS port 8000 (outgoing) UDP for Reliable Stream.

Note that on the 3DS side the UDP port is 8000 whereas on the viewer's side it's the port number you can choose in the settings (defaulting to 8001).

Is it possible for you to post your relevant iptables rules here to double check?

Snickerstream should work under wine from my testing and according to the release note, not sure why it's crashing for you.

The iptable rules

 ❯ sudo iptables -L -n | grep ":8001"
ACCEPT     udp  --  0.0.0.0/0            0.0.0.0/0            udp dpt:8001
ACCEPT     udp  --  0.0.0.0/0            0.0.0.0/0            udp dpt:8001
ACCEPT     udp  --  0.0.0.0/0            0.0.0.0/0            udp dpt:8001
ACCEPT     udp  --  0.0.0.0/0            0.0.0.0/0            udp dpt:8001

And the snickerstream output

If it changes anything, im on nixos

[xzn]

I don't have experience with NixOS. Have you tried creating a new wine prefix for snickerstream?

For iptables, do you have log for when the connections/packets are dropped by the firewall? Just to double check those rules are for the INPUT chain right?

Edit:

Another thing for iptables, those rules you showed were inserted at the top instead of being appended at the bottom right?
