Iโve run a small public web server for well over a decade and never had any issues with hackers.
It's never late to get hacked or an attack or a problem with your ISP router firmware. I don't think that's an excuse.
receive backups from my other servers
You can simply do cronjob and scp user@server:/path/to/backup .
to get things from server to your local network, I don't see the need to expose your router to the public. For a web server, there are cheap VPS providers for less than 5 dollars a month, and you save up energy, hardware, and improve safety at home.
You are welcome, thanks also for asking my opinion about this too.
My post isn't a "constructive" contribution, neither a "destructive" opinion. I might just be rude saying that with those words, but I didn't insult anyone or anything, I just said I disliked it and that I took a good decision to move after reading this. ๐ซค I do like the Fedi, I suppose you can get it.
