OSX: Cannot listen on ports < 1024

I need to investigation how and if this can be fixed. Mockoon being an Electron app I can run Nodejs elevated sub processes but I am not sure how I can do that with npm libs (I use ExpressJS to create the server)

If impossible to solve I could add an option to set a port forwarding using ncat https://apple.stackexchange.com/questions/37418/how-can-i-open-port-80-so-a-non-root-process-can-bind-to-it

Netcat I do not believe is native to OSX but you can use the built in 'pf' to redirect ports as follows:
From 443 to 4443

echo "
rdr pass inet proto tcp from any to any port 4443 -> 127.0.0.1 port 443
" | sudo pfctl -ef -

@naegelin thank you. I think this would be a good compromise. Apparently running a Node sub process elevated is not a big deal, but not sure how I would do this with an npm package while maintaining the connection with the Electron app... (to update the UI).
So it could be one option per environment saying something like "Forward from " with an input to specify the port, then the command would be run elevated so the OS would prompt you.
What do you think ?

This won't be implemented for now. While it would be an interesting addition it didn't gather enough attention. Also, I don't want to mess up with users system files or configs.
If this gather more attention in the future (through votes) I will reconsider.
