Roon 2.0 without outside access

Will Roon 2.0 work if I don’t setup my home network to use Roon from outside? I am seriously concerned of security issues (we all know there are no way to prevent hackers once you open ports), and second, but not less important, I don’t need it from outside at all.

Run Roon 2.0 but set the ARC port to “0”. Also, make sure your router has UpNP disabled…then what Roon does matters not!
