+# Fail2Ban configuration file
+#
+# Author: Daniel Black
+#
+# This is a included configuration file and includes the definitions for the iptables
+# used in all iptables based actions by default.
+#
+# The user can override the defaults in iptables-common.local
+#
+# Modified: Alexander Koeppe <format_c@online.de>, Serg G. Brester <serg.brester@sebres.de>
+#       made config file IPv6 capable (see new section Init?family=inet6)

+# Option:  actionflush
+# Notes.:  command executed once to flush IPS, by shutdown (resp. by stop of the jail or this action)
+# Values:  CMD
+#
+actionflush = <iptables> -F f2b-<name>
+
+
+[Init]
+
+# Option:  chain
+# Notes    specifies the iptables chain to which the Fail2Ban rules should be
+#          added
+# Values:  STRING  Default: INPUT
+chain = INPUT
+
+# Default name of the chain
+#
+name = default
+
+# Option:  port
+# Notes.:  specifies port to monitor
+# Values:  [ NUM | STRING ]  Default:
+#
+port = ssh
+
+# Option:  protocol
+# Notes.:  internally used by config reader for interpolations.
+# Values:  [ tcp | udp | icmp | all ] Default: tcp
+#
+protocol = tcp
+
+# Option:  blocktype
+# Note:    This is what the action does with rules. This can be any jump target
+#          as per the iptables man page (section 8). Common values are DROP
+#          REJECT, REJECT --reject-with icmp-port-unreachable
+# Values:  STRING
+#blocktype = REJECT --reject-with icmp-port-unreachable
+blocktype = DROP
+
+# Option:  returntype
+# Note:    This is the default rule on "actionstart". This should be RETURN
+#          in all (blocking) actions, except REJECT in allowing actions.
+# Values:  STRING
+returntype = RETURN
+
+# Option:  lockingopt
+# Notes.:  Option was introduced to iptables to prevent multiple instances from
+#          running concurrently and causing irratic behavior.  -w was introduced
+#          in iptables 1.4.20, so might be absent on older systems
+#          See https://github.com/fail2ban/fail2ban/issues/1122
