I'm having trouble addressing Neo4j via a reverse proxy with NGINX.

The web client works without problems, but I have no idea about the Bolt protocol.

Here's how the web client works:

server {
    listen 80;
    server_name XXX;

    location / {
        proxy_pass http://YYY:7474/;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header Host $http_host;
        proxy_redirect off;
        proxy_buffering off;
    }
}

But how does the Bolt protocol over port 7687 work?

Thanks.

PS: Google translator ftw.

You need to use nginx compiled with --with-stream. Then you can add below section to your nginx config

stream {
  server {
    listen 7687;
    proxy_pass neo4j:7687;
  }
}

Basically you need to use tcp reverse proxy and not http proxy. The above configuration section will be at top level and not inside http or server block
