Service ports¶

This reference documents all ports used by DUMB services. Use this guide to configure firewall rules, reverse proxies, and understand network requirements.

Service UI access

Most service UIs require the port to be exposed in your compose file before you can access them directly. The exceptions are when you route traffic through a reverse proxy or use DUMB’s embedded UIs via Traefik.

Dynamic port reassignment

On startup, DUMB checks enabled-service ports for conflicts and availability. If a port is already in use, DUMB automatically shifts that service to the next free port and saves the updated value to dumb_config.json. This applies to single-port services and NzbDAV's frontend_port/backend_port.

DUMB core services¶

DUMB API¶

Property	Value
Port	8000
Type	REST API
Protocol	HTTP

The backend API that powers service management, configuration, and monitoring.

http://localhost:8000/api/...

DUMB Frontend¶

Property	Value
Port	3005
Type	Web UI
Protocol	HTTP

The main dashboard for managing DUMB services.

http://localhost:3005

Traefik proxy¶

Property	Value
Port	18080
Type	Reverse Proxy
Protocol	HTTP

Provides unified access to embedded service UIs when enabled.

http://localhost:18080/service/ui/<service_name>

Media servers¶

Plex Media Server¶

Property	Value
Port	32400
Type	Web UI / API
Protocol	HTTP/HTTPS

http://localhost:32400/web

Jellyfin¶

Property	Value
Port	8096
Type	Web UI / API
Protocol	HTTP

http://localhost:8096

Emby¶

Property	Value
Port	8096
Type	Web UI / API
Protocol	HTTP

http://localhost:8096

Content management¶

Riven¶

Component	Port	Type
Backend	8080	API
Frontend	3000	Web UI

http://localhost:3000  # Frontend
http://localhost:8080  # API

CLI Debrid¶

Component	Port	Type
CLI Debrid	5000	Web UI
CLI Battery	5001	API

http://localhost:5000

Decypharr¶

Property	Value
Port	8282
Type	Web UI
Protocol	HTTP

http://localhost:8282

NzbDAV¶

Component	Port	Type
Frontend	3000	Web UI
Backend	8080	API

http://localhost:3000  # Frontend

NzbDAV port overlap

The default NzbDAV ports (3000 and 8080) overlap with Riven defaults. If you run both services, change one set of ports to avoid conflicts.

Arr suite¶

The Arr applications support multiple instances for different workflows (Decypharr vs NzbDAV).

Firewall configuration¶

Minimum required ports¶

For basic DUMB operation, expose these ports:

Port	Required For
3005	DUMB Frontend
8000	DUMB API

Full access¶

For complete functionality including all service UIs:

# Example UFW configuration
sudo ufw allow 3005/tcp  # DUMB Frontend
sudo ufw allow 8000/tcp  # DUMB API
sudo ufw allow 18080/tcp # Traefik (embedded UIs)
sudo ufw allow 32400/tcp # Plex

Use Traefik for consolidated access

Instead of exposing all service ports, enable embedded UIs and access services through Traefik on port 18080. See Embedded UIs.
