i am the only one who can connect to my machine. i use my ddns address and can coonect but anyone outside of the network cannot connect
Let’s start by checking if the port Valheim uses is actually open and listening. You can do this by running:
ampinstmgr ports [INSTANCENAME]
This will check the open ports for your Valheim instance. Replace [INSTANCENAME] with the actual name of your instance.
Could you please share the output of that command?

Hey! Let’s start with the basics. Can you confirm if your server’s ports are open and properly forwarded on your router? Also, check if the firewall settings on your machine allow traffic on those ports. You can often see the needed ports in the AMP interface.
Let me know if you need help with any of these steps!

Alright, let’s tackle the firewall settings on Debian. Here’s a quick way to check and configure them:
Check the status of the firewall:
Open a terminal and run:
sudo ufw status
Allow the necessary ports:
If UFW (Uncomplicated Firewall) is active, you can allow the ports needed by Valheim (default is 2456-2458) with:
sudo ufw allow 2456:2458/udp
Check if the rules are applied:
Run the status command again:
sudo ufw status
Let me know how it goes!

No worries! If UFW isn’t installed, there might still be iptables rules in place. Let’s check and allow the necessary ports using iptables:
Check current iptables rules:
Open a terminal and run:
sudo iptables -L
Allow the necessary ports:
To allow the default Valheim ports (2456-2458), run:
sudo iptables -A INPUT -p udp --dport 2456:2458 -j ACCEPT
Save the iptables rules:
To make sure the rules persist after a reboot, save them using:
sudo sh -c "iptables-save > /etc/iptables/rules.v4"
Verify the changes:
Run the first command again to ensure the rules are applied:
sudo iptables -L
Give that a shot and let me know if that helps!

Got it! Thanks for the heads-up. If you can paste any error messages or logs as text, that would be super helpful. 
In the meantime, did you get a chance to check the iptables settings as mentioned?
