+# The backend talks to game servers through the address that is advertised to
+# browsers (servers.<key>.address, e.g. localhost:7192). Inside the backend
+# container "localhost" is the container itself, not the game container, so
+# with AL_GAME_RELAY=1 a small TCP forwarder publishes the game port on
+# 127.0.0.1 for the backend only.
