Hoping someone can help me with this urgent issue.

All of the sudden, our ecommerce site stopped making connections to PayPal.

I think the issue may be with CSF for some reason (happened overnight) but I cannot figure out how to troubleshoot it.

1. Port 443 is listed in the TCP_IN and TCP_OUT configuration.

2. The nslookup for paypal is fine:

nslookup paypal.com
Server: 10.0.80.11
Address:...

I have a web site that I do not want to be accessed from outside of our local network.

It resides on it's own IP address, so I used the Deny Server Ips feature to block all traffic on it's public IP.

But I can still access it from anywhere.

I notice that the purpose of this feature is to allow blocking of all traffic on server configured IP’s if they’re not in use .

Does that mean that if an...

Hello,

Could someone tell me how to make all together the:
CSF smtp auth +
localhosts +
tls cipher
- part of the rules in the
auth_advertise_hosts= section
of exim.conf?

auth_advertise_hosts =
localhost : ${if eq{$tls_in_cipher}{}{}{*}}
${if match_ip{$sender_host_address}{iplsearch;/etc/exim.smtpauth}{*}{}}

So these two lines should work together in the auth_advertise_hosts rule of...

As indicated:

Is there any guidance or roadmap from CSF on --gulp-- firewalld, or other, as RHEL seems to indicate these may be dropped in the next version.

Thank you.

I am running a WHM CloudLinux8 based dedicated server that has both ModSecurity and CSF/LFD (v14.22) installed.

Despite being set-up correctly as far as I can see, CSF is neither temporarily nor permanently blocking any repeat offender IPs recorded by ModSec in the server's main error_log

I can see lots of IP entries and rules matches in WHM > ModSecurity > Tools so I know ModSec is working....

Something has happened overnight and blocklists cant be downloaded.

One of client informed me that, he is unable to access their site hosted in my server. I then accessed their PC using anydesk, their IP was in firewall whitelist still they were unable to access. I then stopped the firewall using command line and it started working, then started the firewall and it stopped working again. I then stopped CSF and started the firewall from WHM menu and then it was...

Since the Comodo ruleset is dead, I'm trying to switch over to OWASP.
Mod_Security & the OWASP ruleset are installed on a CWP server.

But when I do, LFD doesn't send the email alert or add it to the csf.deny

CSF setting are:

LF_MODSEC = 5
LF_MODSEC_PERM = 1

I have tried different paths of MODSEC, the default is:
MODSEC_LOG = /usr/local/apache/logs/error_log
and
MODSEC_LOG =...

I see that csf blocked ips are logged in /var/log/messages.
Is there a way to have it log the name of the blocklist that triggered the block?
I am using /etc/csf/csf.blocklists to specify blocklists.
something like iptables LOG --log-prefix some name: ?

thanks.

Hi!
Newbi on CSF
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'm trying to switch over from the Comodo ruleset (Since they are dead now) to OWASP.
CSF/LFD is being used with CWP (Control Web Panel).

Need some help.

I use to get LFD notifications and automatic blocks when using Comodo, but now I get neither.

/etc/csf/csf.conf shows:

LF_MODSEC = 5
LF_MODSEC_PERM = 1

MODSEC_LOG = /usr/local/apache/logs/error_log

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 noticed a lot of cloudflare IP's accessing my site. I added them to my csf.deny file but see they are still accessing my site.

Any ideas why they can still access the site? Been using csf successfully prior to this.

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
