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.
Hopefully you’re only forwarding the minimal select of network ports and not all ports/traffic? If so then you’re good, like someone else said if you’ve got a router and it’s forwarding selected traffic then no need for anything else
