Let IPTABLES_IPSET_RULE_NUMBER=1 # if FORCE is yes, the number at which place insert the ipset-match rule (default to 1) VERBOSE=yes # probably set to "no" for cron jobs, default to yesįORCE=yes # will create the ipset-iptable binding if it does not already exist IP_BLACKLIST_EXCEPTIONS=/etc/ipset-threatblock/threatblock.exceptions IP_BLACKLIST=/etc/ipset-threatblock/ip-threatblock.list IP_BLACKLIST_RESTORE=/etc/ipset-threatblock/ip-threatblock.restore # ensure the directory for IP_BLACKLIST/IP_BLACKLIST_RESTORE exists (it won't be created automatically) # eg: updatethreatblock.sh /etc/ipset-threatblock/nfįunction exists() -tmp Now everything should be switched over to iptables and CSF should function correctly.The following configuration protects a debian head end from defined threats. Go to the Juggernaut Firewall -> Settings -> Binary Settings and press the default button at the bottom of the page to apply the correct iptables binary locations.

There are 2 choices for the alternative iptables (providing /usr/sbin/iptables).ġ /usr/sbin/iptables-legacy 10 manual mode To view your alternatives for running iptables you can run the command: update-alternatives -config iptables # update-alternatives -config iptables For iptables-nft, the variant will be shown in parentheses after the version number, denoted as nf_tables: # iptables -Vġ. You can find out which variant is in use by looking up the iptables version. The newer iptables-nft command provides a bridge to the nftables kernel API and infrastructure and is recommended if it is supported by your OS. nf_tables: Often referred to as iptables-nft. ![]() legacy: Often referred to as iptables-legacy.Ģ. There are two variants of the iptables command:ġ. Make sure that the iptables packages are installed: # apt-get install iptables Most of the newer OS support iptables-nft which provides a bridge to the nftables kernel API and infrastructure so using iptables isn't an issue. ConfigServer Security & Firewall (csf) currently supports using iptables interface so when upgrading to Debian 11, Ubuntu 20.04 LTS, or Ubuntu 22.04 LTS which uses nftables by default you must switch back to the iptables interface.
