The /usr/local/csf/bin/regex.custom.pm file allows you to set up blocking for failed Wordpress login attempts, for example:

if (($globlogs{CUSTOM2_LOG}{$lgfile}) and ($line =~ /(\S+).*] \w*(?:GET) \/wp-login\.php.* /)) {
return ( Failed WordPress GET ,$1, WPLOGINGET , 5 , 80,443,21,25,22,23 , 1 );
}
if (($globlogs{CUSTOM2_LOG}{$lgfile}) and ($line =~ /(\S+).*] \w*(?:POST) \/wp-login\.php.* /))...

Hi all! :)

I just wanted to confirm whether wildcards are supported in csf.redirect or not. The documentation seems to suggest that they are, but I get this:

Error: csf: Invalid csf.redirect format , at line 3249

With this:

Testing ip_tables/iptable_filter...OK
Testing ipt_LOG...OK
Testing ipt_multiport/xt_multiport...OK

I added several repeat offender ASN's to CC_DENY. Was really excited about this because it could make my life a lot easier.

However, I was dismayed to see IP's from within those ASN's still hitting Apache. The field is setup like this:

CC_DENY = AS12345, AS23456, AS34567

Is this the proper format? I added 20 ASN's, are there any settings to adjust to allow so many? Perhaps DENY_IP_LIMIT? I'm...

Hi all!
We have these settings in place in CSF configuration file:

LF_DISTSMTP = 5
LF_DISTSMTP_UNIQ = 3
LF_DISTSMTP_PERM = 1
LF_DISTSMTP_ALERT = On
LF_DIST_INTERVAL = 300

And some DISTSMTP triggers have been intercepted because of some customer of ours having used Gmail for sending mail messages via our server's MTA.

So we received some mail warings (subj: distributed SMTP Logins on account...

Hi, I'm new to the forum and was clicking around a few of the pinned topics, and noticed that at least one has a dead link:

The link at the bottom is but I assume the forum migrated at some point to the new link format with viewtopic.php instead. Substituting viewtopic for showthread in the link pulls up what appears to be the correct link.

Maybe the DB could be search/replace for this to do...

Hi, I have some servers acting as Wireguard endpoints that need to accept traffic from certain ports and forward them to another host on a LAN at the other end of the Wireguard tunnel. Incoming data on the ports are accepted and forwarded to the appropriate host. Outgoing data is masqueraded. The TCPMSS clamp is required to ensure the forwarded packets respect the tunnel MTU. In this case as you...

I've got a user that keeps getting blocked for a custom LFD rule to block 3 consecutive Worpress failed logins within 3600 seconds. But they swear they are not getting failed logins. The rule is the widely published rule:

if (($globlogs{CUSTOM1_LOG}{$lgfile}) and ($line =~ /(\S+).*] POST \/wp-login\.php.* 200/)) {
return ( Failed WordPress login from ,$1, wordpress , 5 , 80,443 , 3600 );
