[2023] Port Forwarding: Port open until server starts then it's closed

Original Post — Direct link

I'm very confused here. I'm trying to host a server on an extra PC. Typically I just need to set up port forwarded to the needed ports (3000-3002) and everything works. Before I start the server https://www.yougetsignal.com/tools/open-ports/ tells me the port I'm using for the game is open. once the server is running the same tool reports the same port is now closed.

I don't have windows firewall or windows defender enabled. No other virus protection.

Does anyone have an idea what gives?

Can you do an ipv6 address behind a DNS entry and have your friends use the DNS entry? Assuming you can get a cheap domain name. It's a little bit more complex but it sounds like you know what you are doing. Then just allow the ipv6 traffic through your router (assuming you and your friends get ipv6 through your ISP) another option is a VPN, it will add some overhead but it would be better than nothing.

Or if you are feeling brave duel boot into a Linux distro like Ubuntu and try running the Linux version of the server 🤷‍♂️ its pretty easy to do once you get used to Linux

Eco servers don't support IPv6 - you need to have IPv4.

What's the actual error you are getting?
Those online tools are not really suitable to diagnose any problems, once Eco is running, it might simply not be accepting unformatted requests it doesnt expect.

Unfortunately not anytime soon.

The only error I got was when UPnP was enabled. Then I got a error stating the UPnP mapping wasn't created. Disabling UPnP on the server config got rid of that error.

Otherwise, no error. Just states it cannot connect

Yes, but what is the exact error it shows when it can't connect? (It creates a logfile)

Have you tried connecting via the server id? Do you have an IPv4 address from your provider, either natively or through a tunnel? Eco servers do not work with sole IPv6 connections, in such cases you need to get a IPv4 some way or host a server on a connection that does offer it.
