Volumio behind Firewall

Hello together
Please if you have also your Volumio behind your Firewall ?
you add the ip Address from Volumio directly NAT 1:1 to Outsidem or you have any Port Rules?

I think that meny streaming Service will be run with Port 80, but here in this example
what are the best way?


I am not clear what you are asking here. Are you asking if Volumio implements a firewall? Are you trying to access Volumio on a local machine from the internet (remotely)?
