Log all connection attempts when using as reverse proxy

[amokfa]

I use chisel to expose a local port to the internet. There is a -v option for chisel client but it only prints some debug information. I want it to print all incoming connection requests. i.e. Which ip tried to connect to this port. A debug option to also log all the data being tunneled will also be great to have. How feasible is it? I'm willing to work on this.
