CSF Firewall / Re: CSF Doesn't appear to be blocking ports?
« on: February 16, 2019, 05:43:45 AM »
It appears to be working properly now, all ports are now closed when scanning from my home computer. I will have to tray again on Monday from the work computer and confirm I can no longer get through from there also.

In fact, I think I just worked it out. My work computer's IP was automatically whitelisted as that is the IP that I installed CWP from.

Thanks for all your help Netino   ;D

CSF Firewall / CSF Doesn't appear to be blocking ports?
« on: February 15, 2019, 02:45:08 AM »
Hi All,
I am a first time user with a fresh VPS with a fresh install of CWP.
I use CSF firewall on my older VPS with Cpanel and it works well.

O this new VPS I have removed a lot of the standard open ports for IPv4 & IPv6, I will open them when I need them.
However when I run a port scan on my VPS from an external source, the ports are all still open.

Can anyone offer advice as to why this may be? Screenshots below for reference.

Thank you  :)
