nbsberlin, addresses in the 192.168 range are not routable on the Internet so there is not much reason to hide them as you did.
Nobody from the Internet can hack your server if they only know your 192.168 internal address, they would need to know what it maps to on the outside…
From the inside it’s another matter but then people would need to be connected to your network and they could scan each IP to find where your servers are…
Yep. I am aware that 192.168 cannot be publicly routed. Still best practice to hide as much information as possible.
You would not post behind which picture you are hiding your Safe either. I could argue “it is mounted to the wall so it is unlikely it can be publicly routed (aka carried around your street)”. However in the unlikely case that someone makes it behind your “firewall (aka front door)” that information provides some advantage to whoever wants to get to your Safe
