Perhaps obvious answer but I dont find

If I allow 1 country in the allow list and the deny list is empty, does it mean that all countries exept the one allowed is denied

I have the following port range open in TCP-OUT in firewall configuration 49152:65534

I changed from cPanel to CWP Control Panel and I am running the latest version of CSF and everything was fine until the otherday I could not access any domain on my server, yet I can access any IP on the server so when I need to access a domain I have to disable CSF.

I have my IP in csf.allow & csf.ignore and it is still blocking me on Port 80 and I cannot figure out why, anyone have...

None of the mail coming from my customers contact forms are being scanned. When I look at the email in Mailscanner FE it says Not Scanned at the top. Consequently my customers are getting a ton of spam delivered to their inboxes generated from their contact forms. I have searched endlessly but nothing is white listed that I can see that would cause this. The server's IP is whitelisted in CSF, but...

HI I enabled the web UI for CSF, getting connection reset by peer while doing a curl

Hi guys, I'm new here, but I've been using CSF for many years! Over 2024, there has been a surge in Internet attacks and I've recently discovered something with my CSF install that I think is weird and wanted your opinion and eventually maybe a suggestion to mitigate the issue:

In my config, I have:
LF_TRIGGER = 0
LF_APACHE_404 = 200
LF_APACHE_404_PERM = 3600 (1 hour)
LF_INTERVAL = 300 (5...

Hi,

I think CSF doesn't attention to allow list of IPs when we temporary deny an IP address
But it fails deny when we want to deny normally

Thanks

Hi, i already set email notification to off but seem like i still received notification like almost 1k per day.

Hi there,

We allow remote MySQL access for specific IP adress, by adding a rule to the csf.allow file as following;

d=3306|s= #

This has been working fine for a couple of years now.

However, since a few days we got multiple complaints that MySQL access is blocked. When checking the logs I see these entries; indicating that the port is blocked. I have seen multiple cases of this, on...

After the most recent DA update (version 1.672). The Admin interface to MSFE gives this error and no other indication.

CSF was fixed by touch /var/lib/csf/csf.da.skip

Is there a fix coming for MSFE'?

We checked the issue with CS Mail Queue Plugin closer with one of our developers and were able to apply the workaround in the same way as it is applied for CSF PlugIn. Added this 2 lines:

I have CSF configured to block SMTP Auth attacks, syntax errors, and POP3/IMAP access attempts. However, none of those appear to be being blocked at present and only SSH attacks appear to be blocked. I've double checked my configuration and it appears to be correct, but it's like CSF is ignoring it. I installed the software with CPanel but that shouldn't be the reason for that I wouldn't think....

Hello to all,
For the last few weeks, when I try to install a WordPress from a cPanel account, I receive this error:
WordPress was installed with errors:
Downloading and unpacking
Impossible to download pack 6.7.1 from

If I stop or restart CSF, it work for a few minutes, but then block again.

In TCP_IN and TCP_OUT, ports 80 and 443 are listed.

What can possibly do this?

Thank you.
