At some point while running iptables -S on an Ubuntu 18.04.2 LTS system with Fail2ban installed, I noticed that the following lines were missing:



-N f2b-sshd
-A f2b-sshd -j RETURN


What command should I run to regenerate the f2b-sshd chain and all the rules associated with it? I tried running fail2ban-client restart, but this doesn't appear to have any effect.
