You know what it means.

Guide

Server

  1. Go to your domain in CloudFlare. In “Network” tab, turn on gRPC.

  2. In “SSL/TLS” tab, choose “Source Servers” sub tab. Create a new certificate and save as cert.pem and cert.key.

  3. In “DNS” Tab, add a record pointing to your own server. Make sure the proxy state is “Proxied”.

  4. Run and persist this on your server. This example will forward the inbound traffic to 127.0.0.1:8899.

gun -mode server -local :443 -remote 127.0.0.1:8899 -cert cert.pem -key cert.key
  1. If you are using a TLS termination proxy, you can set -cleartext parameter to use HTTP/2 Cleartext transport protocol.

Client

  1. Assume the domain of server is grpc.example.com.

  2. Run locally and persist. This will tunnel connections from 127.0.0.1:8899 to remote.

gun -mode client -local 127.0.0.1:8899 -remote grpc.example.com:443

There’s also a SIP003 plugin version, see it’s document for instruction.
