+## Host-Port Mode
+
+Instead of modifying the Traefik config, 
+you can alternatively deploy Mumble with compose.host-ports.yml,
+and it will bind directly to the host server ports 64738 and 64739,
+bypassing Traefik. 
+
+Note this doesn't work in multinode setups, but does work when deployed to a single server.
+
+With this compose file, you can deploy mumble without any changes to the Traefik config:
+
+1. `abra app config <YOURAPPDOMAIN>` — uncomment the line:
+   ```
+   COMPOSE_FILE="$COMPOSE_FILE:compose.host-ports.yml"
+   ```
+2. `abra app deploy <YOURAPPDOMAIN>`
