I want to host a small game server for friends and myself in my home but doesn’t want to open up the firewall. Any tunneling solutions supports UDP? Thnaks.

Wireguard/Tailscale? (I’m not sure how well they do with latency).
Tailscale and Netbird are what you are looking for. I highly recommend Netbird as it is much more user friendly. Just keep in mind it forwards all ports by default. You can change that in the access policies
i2p also can do it if you need privacy

You might try ZeroTier. You’ll each need a tiny client app, but its super easy to install and setup, and extremely secure. Free to use with up to 25 devices.
Can confirm, very easy to setup clients. And since its not a VPN but a VLAN, you wont run into problems connecting between different clients.
This is pretty much open-source Hamachi.
Most VPNs use UDP. So set up a wireguard, tailscale or openvpn.
But you still need to “open up the firewall”. UDP still works on ports the same way as TCP. I do agree however, that exposing a VPN port is more secure than exposing a port for a game server, as you don’t know about the security of that server software.
Does that require my friends install & configure Tailscale/WG/OpenVPN? I tried that route like 2~3 yrs ago with OpenVPN and it doesn’t works well.
I would like to keep it as simple and easy as it can be. Aka no need extra software and config. Just fireup the game, connect, and play, as if the server is hosted on some VPS.
At some point, you have to compromise.
- You can open the port(s) used by the game on the firewall (assuming you have a publicly routable IP).
- You can run OpenVPN or a proprietary solution, but you’ll have to open a port on the firewall, and I know from experience that they’re a bitch and a half to configure.
- You can run Wireguard, but you’ll have to open a port on your firewall and have the other clients generate and send you their public keys.
- You can run Tailscale, which uses Wireguard and works without opening the firewall, but you’ll have to install the client, have the users sign in, and then add them to your tailnet, which IMO is much easier than setting up Wireguard peers manually.
- You can use Tailscale Funnel, which exposes your tailnet to the public internet, but it’s in beta, has high latency, and only supports TCP.
- You can try Ngrok, which is a similar NAT traversal solution, but it only supports TCP and gives you a different IP and port every time you create a tunnel.
