Agree, if you’re just playing with friends. But if they are opening up invites to their friends, or if you plan to go public, I always recommend multi tiered protection. Especially if your system is used for other activities other than the game server.
thanks for the container by the way, it’s been rock solid!
For those trying to use Proxied cloudflare for dns, the 8211 port is not valid in their proxy support port list. Therefore you must change your external port to a valid port and then port forward that external port to 8211, or change both internal and external ports (not recommended).
OR you can run unproxied by turning off Proxy in the cloudflare DNS settings.
make sure if you have automatic cloudflare dns update scripts that you are also configuring that in alignment with the above.
