I have a host name whose dns points to my home IP. I use this for game servers for my buddies. Should I be worried about my home IP being easily accessible like this, and should I get a physical firewall appliance to protect myself?
Servers are running Windows Server 2019 and Mac OSX.
It depends. If you’re forwarding a lot of ports then maybe, but just a home gaming server? Probably not a big deal.
Just don’t forward ports for remote control and you’ll be fine, especially RDP (3389 IIRC), and SSH…
