 From memory macos server includes a VPN server by default which is 
actually pretty straightforward to setup .  There is a decent 
walkthrough here 
https://www.imore.com/how-setup-your-own-vpn-macos-server .  The one I 
setup a few years back was easier to setup than openvpn on linux.  I am 
not sure if your server is running osx server however.

Regarding openvpn server, you can do it, I have not done it on mac 
personally.  I recommend e.g. this link to give it a go 
https://tinyapps.org/docs/openvpn/

Both of these easier than the work you already did to make the radio app

Cheers

Tim
