FOSS gamedev and creative worlds

before complaining, I want to thank this community for existing. I have not posted much here in the forum but have worked hard in another community and I want to congratulate you all for version 0.4.11.
I configured my minetest server with the following line

but did not work and my ip is exposed.
I use no-ip to mask my real IP.
I realized a check on the minemacro.servegame.com host functioned normally put my real IP remained exposed.
The server took too long to be completed and is now paralyzed on my dedicated server.
Please, help me!!!

address is a client-side setting, use server_address if you want to use a doman when announcing to the server list.

Okay. I do not believe it was wrong.
Thank you very much!
