+## Acceso Externo (fuera de la red local)
+
+### Requisitos
+- Router con acceso al panel de administracion
+- Dominio en Cloudflare (consultoria-as.com)
+- Token de API de Cloudflare con permisos Zone > DNS > Edit
+
+### 1. Crear token de Cloudflare
+1. Ir a https://dash.cloudflare.com/profile/api-tokens
+2. Create Token > Edit zone DNS (template)
+3. Zone Resources: Include > Specific zone > consultoria-as.com
+4. Copiar el token generado a `CF_API_TOKEN` en `docker/.env`
+
+### 2. Configurar variables
+En `docker/.env`:
+```env
+PUBLIC_HOST=play.consultoria-as.com
+CF_API_TOKEN=tu-token-aqui
+```
+
+En `servers/maple2/.env`:
+```env
+GAME_IP=play.consultoria-as.com
+LOGIN_IP=play.consultoria-as.com
+```
+
+### 3. Port forwarding en el router
+Abrir estos puertos TCP en el router, apuntando a la IP local del servidor (192.168.10.234):
+
+| Puerto | Servicio | Protocolo |
+|--------|----------|-----------|
+| 23000 | OpenFusion (login) | TCP |
+| 23001 | OpenFusion (shard) | TCP |
+| 20001 | MapleStory 2 (login) | TCP |
+| 20002 | MapleStory 2 (game) | TCP |
+| 25565 | Minecraft FTB Evolution | TCP |
+
+**No forwardear**: PostgreSQL (5432), MinIO (9000/9001), Strapi (1337), Next.js (3000), MySQL (3307). Estos son servicios internos.
+
+### 4. Levantar servicios
+```bash
+cd docker
+docker compose -f docker-compose.dev.yml up -d
+docker compose -f docker-compose.maple2.yml up -d
+```
+
+El contenedor `cloudflare-ddns` actualizara automaticamente el registro DNS `play.consultoria-as.com` con tu IP publica cada 5 minutos.
+
+### 5. Conexion desde fuera
+| Juego | Direccion |
+|-------|-----------|
+| Minecraft FTB Evolution | `play.consultoria-as.com:25565` |
+| OpenFusion (FusionFall) | `play.consultoria-as.com:23000` |
+| MapleStory 2 | `play.consultoria-as.com:20001` |
+
 ### Detener servicios
 ```bash
 docker compose -f docker-compose.dev.yml down
