Relay server configuration

Fields

base_domain: String

Base domain for tunnels (e.g., “relay.example.com”)

listen_addr: SocketAddr

Listen address

request_timeout: Duration

Request timeout

max_tunnels_per_ip: usize

Maximum tunnels per IP (rate limiting)

use_https: bool

Whether to use HTTPS for tunnel URLs

auth_tokens: HashSet<String>

Valid API tokens for authentication (empty = no auth required)

require_auth: bool

Whether authentication is required

jwt_secret: Option<Vec<u8>>

JWT secret for token-based auth (None = use simple token matching)

jwt_validity: Duration

JWT token validity duration

auth_rate_limit: AuthRateLimitConfig

Auth rate limiting configuration

max_tunnel_age: Option<Duration>

Maximum tunnel age (TTL) - tunnels older than this are closed None = no limit (tunnels live until disconnected)

max_idle_time: Option<Duration>

Maximum idle time before tunnel is closed None = no idle timeout

allow_custom_ids: bool

Allow custom tunnel IDs (if false, only random IDs are allowed) Set to false for public relays to prevent subdomain squatting
