Okay... have you any idea how to improve the line
	@subchain "fail2ban-SSH" { RETURN; }
in order to make it acceptable. :-)

	proto tcp @subchain "fail2ban-SSH" { RETURN; }
fails

	jump @subchain "fail2ban-SSH" { RETURN; }
fails

	saddr @ipfilter((0.0.0.0/0 ::/0)) @subchain "fail2ban-SSH" { RETURN; }
works but I guess consumes more CPU time than necessary
