Custom Logs not triggering CloudFlare block

[yoshi_fp]

Hello,

I noticed that CSF now supports blocking at the CloudFlare level which is great, however I'm trying to use a custom log with a custom regex to trigger a block in CloudFlare and this doesn't seem to be working.

I've tried with it set as a permanent block and a temporary block but neither of these are triggering the API call to CloudFlare. I'm not using cPanel, just plain CentOS.

I have my custom rules triggering correctly and showing in my logs and getting emails stating they've been activated but then I check CloudFlare and nothing is appearing in there. I've tested the API connection to CloudFlare on the command line with csf --cloudflare function and these are all working.

Below is a sample from the config changes I've made, to get this all working.

• Installed LWP (requirement for CloudFlare)

• In /etc/csf/csf.conf
  
  modify:
  • URLGET
    1
    to
    2
  • CF_ENABLE
    0
    to
    1
  • CF_TEMP
    3600
    to
    86400
  • LF_TRIGGER
    "0"
    to
    "10"
    Trigger custom rule after this many login failure/custom log attempts/entries
  • LF_TRIGGER_PERM = "86400"
    CUSTOM1_LOG
    "/var/log/customlog"
    to
    "/var/log/httpd/sites_access_log"
  • Set CloudFlare settings in /etc/csf/csf.cloudflare
    • DOMAIN:any:USER:--linux_username---:CFACCOUNT:--Cloudflare_username--:CFAPIKEY:--Cloudflare_API_KEY--{/list]
  I am seeing these entries in my logs, and have checked CloudFlare and the local csf for the IPs being blocked, not appearing in CloudFlare but are appearing the local csf.

  I have since removed from the local csf with csf -dr and csf -tr after I checked they were not present in CloudFlare.
  
  My custom regex similar to this:
  
  if (($globlogs{CUSTOM1_LOG}{$lgfile}) and ($line =~ /(\S+).*"GET \/index\.php\/(site\/login).*" (401|403)/))
  {
  return ("MyApp Login Failure",$1,"CustLoginFailMyApp","80,443",86400)
  }
  
  Is there a simple configuration problem I have here or do Custom Logs not trigger CloudFlare blocks, or do I need to include something else inside the regex match before returning, or do I need to return different parameters to the function in return on the custom regex?
  
  Thanks in advance

The cloudflare blocking will only trigger on LF_MODSEC and LF_CXS, not the custom triggers.
