IP Block Lists

IP Block Lists allows CSF/LFD to periodically download lists of IP addresses and CIDRs from published block lists. It is controlled by the file /etc/csf/csf.blocklists. Uncomment the line starting with the rule name to use it, then restart CSF and then LFD.

• After making any changes to /etc/csf/csf.blocklists you must restart CSF and then LFD.
• If you want to re-download a blocklist you must first delete /var/lib/csf/csf.block.NAME and then restart CSF and then LFD.
• Each URL is scanned for an IP address/CIDR address per line and if found is blocked.

Format

NAME|INTERVAL|MAX|URL
Parameter Description
NAME List name with all uppercase alphabetic characters with no spaces and a maximum of 25 characters - this will be used as the iptables chain name.
INTERVAL Refresh interval to download the list, must be a minimum of 3600. seconds (an hour), but 86400 (a day) should be more than enough.
MAX This is the maximum number of IP addresses to use from the list, a value of 0 means all IPs.
URL The URL to download the list from.

• Make sure that your server supports IPset and that IPset is enabled under Juggernaut Firewall -> Settings -> General Settings before enabling these lists.
• For large lists remember to set the max IP address limit for the blocklist to be under 65536 (otherwise you will get ipset errors). Alternatively you can raise the ipset limit under Juggernaut Firewall -> Settings -> General Settings -> Ipset maxelem.
• These lists are not under the control of Danami and could have false positives.
