# OBP proxy (single inbound port)
|
||||
|
||||
Optional `OBP_PROXY` stanza configures the fan-in listener for all `MODE: OPENBRIDGE` systems. When active, OpenBridge instances are **inject-only** (no per-bridge `listenUDP` in `HBPProtocol`); the proxy owns every inbound OBP socket.
|
||||
|
||||
## Activation
|
||||
|
||||
| YAML | Behaviour |
|
||||
|------|-----------|
|
||||
| No `OBP_PROXY` block, no OPENBRIDGE | N/A (proxy not started). |
|
||||
| No `OBP_PROXY` block, OPENBRIDGE present | **Default proxy on** (`LISTEN_PORT` 62032, `BIND_LEGACY_PORTS` true). |
|
||||
| `OBP_PROXY.ENABLED: false` | Legacy mode: each OPENBRIDGE binds its own `PORT`. |
|
||||
| `OBP_PROXY.ENABLED: true` | Proxy manages all OBP inbound UDP (same as absent block). |
|
||||
|
||||
## Configuration
|
||||
|
||||
```yaml
|
||||
OBP_PROXY:
|
||||
ENABLED: true
|
||||
LISTEN_PORT: 62032 # ADN standard OBP fan-in (pair to PROXY 62031)
|
||||
LISTEN_IP: "" # optional bind address
|
||||
BIND_LEGACY_PORTS: true # default: also listen each SYSTEMS.*.PORT
|
||||
DEBUG: false
|
||||
```
|
||||
|
||||
OPENBRIDGE sections stay unchanged (`PORT`, `NETWORK_ID`, `PASSPHRASE`, `TARGET_*`, ACL, etc.). With proxy enabled, `PORT` is kept as metadata (`_REPORT_PORT` internally) for monitor/report and optional legacy listeners.
|
||||
|
||||
## Per-bridge migration (`BIND_LEGACY_PORTS: true`)
|
||||
|
||||
When the global flag is true, each OPENBRIDGE can migrate individually:
|
||||
|
||||
| `SYSTEMS.*.PORT` | Behaviour |
|
||||
|------------------|-----------|
|
||||
| Same as `OBP_PROXY.LISTEN_PORT` (e.g. 62032) | Fan-in only for this bridge (no extra legacy listener). |
|
||||
| Omitted, `0`, or empty | Same as `LISTEN_PORT` — fan-in only (migrated bridge). |
|
||||
| Any other port (e.g. 62999) | Legacy listener stays open for that bridge. |
|
||||
|
||||
Example: migrate `OBP-CL2` to the shared fan-in while `OBP-EU` keeps `PORT: 62999`.
|
||||
|
||||
## Migration
|
||||
|
||||
1. Existing configs with OPENBRIDGE but no `OBP_PROXY` stanza already use defaults (`BIND_LEGACY_PORTS: true`) — no remote changes required.
|
||||
2. Optionally add an explicit `OBP_PROXY` block to tune `LISTEN_PORT` / `BIND_LEGACY_PORTS`.
|
||||
3. Set `BIND_LEGACY_PORTS: false` and close legacy ports when all remotes use `LISTEN_PORT`.
|
||||
|
||||
## Requirements
|
||||
|
||||
- `NETWORK_ID` must be unique among enabled OPENBRIDGE systems.
|
||||
- `LISTEN_PORT` must not collide with any OPENBRIDGE `PORT` when `BIND_LEGACY_PORTS` is true.
|
||||
- `RELAX_CHECKS: true` is recommended so `TARGET_SOCK` is learned from the first valid packet.
|
||||

||||

# Proxy OBP (puerto de entrada único)
|
||||
|
||||
La stanza opcional `OBP_PROXY` configura el listener fan-in para todos los sistemas `MODE: OPENBRIDGE`. Con el proxy activo, las instancias OpenBridge son **inject-only** (sin `listenUDP` por bridge en `HBPProtocol`); el proxy gestiona todo el UDP OBP entrante.
|
||||
|
||||
## Activación
|
||||
|
||||
| YAML | Comportamiento |
|
||||
|------|----------------|
|
||||
| Sin `OBP_PROXY`, sin OPENBRIDGE | N/A (no se arranca proxy). |
|
||||
| Sin `OBP_PROXY`, con OPENBRIDGE | **Proxy por defecto** (`LISTEN_PORT` 62032, `BIND_LEGACY_PORTS` true). |
|
||||
| `OBP_PROXY.ENABLED: false` | Modo legacy: cada OPENBRIDGE hace bind en su `PORT`. |
|
||||
| `OBP_PROXY.ENABLED: true` | El proxy gestiona toda la entrada OBP (igual que bloque ausente). |
|
||||
|
||||
## Configuración
|
||||
|
||||
```yaml
|
||||
OBP_PROXY:
|
||||
ENABLED: true
|
||||
LISTEN_PORT: 62032 # puerto estándar OBP fan-in (pareja de PROXY 62031)
|
||||
LISTEN_IP: "" # dirección de bind opcional
|
||||
BIND_LEGACY_PORTS: true # default: también escucha cada SYSTEMS.*.PORT
|
||||
DEBUG: false
|
||||
```
|
||||
|
||||
Las secciones OPENBRIDGE no cambian (`PORT`, `NETWORK_ID`, `PASSPHRASE`, `TARGET_*`, ACL, etc.). Con proxy activo, `PORT` se conserva como metadato (`_REPORT_PORT` internamente) para monitor/report y listeners legacy opcionales.
|
||||
|
||||
## Migración por bridge (`BIND_LEGACY_PORTS: true`)
|
||||
|
||||
Con el flag global activo, cada OPENBRIDGE migra de forma individual:
|
||||
|
||||
| `SYSTEMS.*.PORT` | Comportamiento |
|
||||
|------------------|----------------|
|
||||
| Igual a `OBP_PROXY.LISTEN_PORT` (p. ej. 62032) | Solo fan-in para ese bridge (sin listener legacy extra). |
|
||||
| Omitido, `0` o vacío | Igual que `LISTEN_PORT` — solo fan-in (bridge migrado). |
|
||||
| Otro puerto (p. ej. 62999) | Se mantiene el listener legacy de ese bridge. |
|
||||
|
||||
Ejemplo: migrar `OBP-CL2` al fan-in compartido mientras `OBP-EU` conserva `PORT: 62999`.
|
||||
|
||||
## Migración
|
||||
|
||||
1. Configs existentes con OPENBRIDGE sin stanza `OBP_PROXY` ya usan defaults (`BIND_LEGACY_PORTS: true`) — sin cambios en remotos.
|
||||
2. Opcionalmente añadir bloque `OBP_PROXY` explícito para ajustar `LISTEN_PORT` / `BIND_LEGACY_PORTS`.
|
||||
3. `BIND_LEGACY_PORTS: false` y cerrar puertos legacy cuando todos usen `LISTEN_PORT`.
|
||||
|
||||
- `NETWORK_ID` único entre OPENBRIDGE habilitados.
|
||||
- `LISTEN_PORT` sin colisión con ningún `PORT` de sección si `BIND_LEGACY_PORTS` es true.
|
||||
- `RELAX_CHECKS: true` recomendado para aprender `TARGET_SOCK` del primer paquete válido.
