Firewall

Help! (Home for newbies)

Hi guys!

I finally got my sites up and running and things are working just great! My question is: should I be running some sort of firewall for security and if so which one would you folks recommend?

If someone could point me in the right direction I’d be grateful.

Depends on your O\S. I use iptables and happy enough with it, along with Fail2Ban.

I’m on Ubuntu server 18.04. That Fail2Ban software installed with the Virtualmin install, so am I good to go as is?

Thanks!

Fail2Ban needs (usually) configuring to suit your purposes.

OK. I’ll look into doing that then. Thank you!
