forward abstract method
Publishes http://[localAddress]:[localPort] on the public internet.
publicPort defaults to 443. Tailscale currently allows Funnel only on
policy-approved ports (commonly 443, 8443, and 10000; see
https://tailscale.com/docs/features/tailscale-funnel); unsupported ports throw
TailscaleFunnelException with a structured error code where the native
runtime can classify it.
localAddress must be loopback (127.0.0.1, ::1, or localhost).
This prevents accidentally publishing arbitrary LAN or metadata-service
endpoints to the public internet.
Implementation
Future<TailscalePublishedService> forward({
required int localPort,
int publicPort = 443,
String localAddress = '127.0.0.1',
String path = '/',
});
