    One question I have here is the process of sending an encrypted network package.
    
    The LAN backend did something where it seemed to send the port to listen on in an unencrypted manner, and then encrypted the package and sent it on that port. Here, I'm encrypting the package first and then just sending over the payload. Will this (combined with the logic around line 90 above) work?
