Without going on a rant. UnRAID doesn’t really have a firewall, so you end up deping on a latlyer 2 firewall. And depending on your router, you may be SOL. When you port forward, you basically open the route on fron your router’s firewall. At that point, you depend on if the application is secure now the attack vector is as wide as the intention of the attacker. Unraid is a pain when it’s down to security anyways.
Whith the way rhel is l taking. Home use in production is terrible idea
