Expose Multiple Interfaces

Services often need more than a web UI — RPC endpoints, peer-to-peer connections, WebSocket servers, SSH, or admin dashboards on separate ports. Each interface gets its own MultiHost, port binding, and interface descriptor.

Solution

In setupInterfaces(), create separate MultiHost instances for each interface (web UI, API, peer). Each gets its own bindPort() call with appropriate protocol settings — protocol: 'http' for web, protocol: 'https' with addSsl for APIs, protocol: null with secure: { ssl: false } for raw TCP. Create interfaces with type: 'ui', type: 'api', or type: 'p2p' as appropriate. Use masked: true for interfaces whose URLs contain credentials.
