SteamCMD reverse proxy for multiple dedicated servers

I have a home server where I plan to host multiple game servers. I
want to allow steam to use the 27016 to find all the servers, but that
means I have to discern the game servers by IP, and I can't do that.
What I can however, is set up different subdomains, which all point to
the same IP. I have Nginx Proxy Manager to handle HTTP reverse proxy
connections based on the hostname, and for MKinecraft servers I can
use Bungeecord or Velocity. Is there a similar solution for SteamCMD
games?

TL;DR: How can I setup a reverse proxy for SteamCMD games so that all
games can be discovered but then proxied to their own port when
connecting?

UDP ha no concept of a hostname, you can't reverse proxy a single IP
to multiple UDP backends, you can only proxy multiple ports to
different end ports.

Yeah what the other poster said. I tried to do the same thing with my
game servers and unfortunately, it's just not possible with UDP.

You cant do that, each steam server needs its own external IP to
access steam services in both directions.
