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.
If you want any system to connect to you, you need to open a port. You don’t need to do that for outgoing connections (the OS and your router will automatically open ports for the return connection). So if everybody connects to one central system, nobody needs to (explicitly) open any ports (except for the central connection point)

Thats one of the neat features of tailscale and zerotier, they can set it up so both ends are “outgoing” to the NAT so no port forwarding is needed
