Using auth.json file with target verification

Hi

I'm using a reversed chisel server with an auth.json file, for example:

{
      "user1:123": ["R:0.0.0.0:5555"]
}

On some remote machine I'm running chisel client with the following command:
.\chisel client --auth "user1:123" <my-server-ip> R:0.0.0.0:5555:<remote-server-ip>

Everything works fine with this setup and the chisel client is authenticated and is limited to 0.0.0.0:5555 only, however I would also like to limit the remote server (<remote-server-ip>) so that the chisel server will only allow port forwarding to closed set of remotes per user, is there a way to do it as well?

Thanks

Start by tracing how the server reads auth.json and how the client command's remote-server-ip target is validated. Determine whether per-user restrictions can cover both the forwarded local port and remote destination, then document the expected configuration and verification behavior.
