+# Changing iptables rules requires root privileges. If fail2ban is
+# configured to run as root, firewall setup can be performed by
+# fail2ban automatically. However, if fail2ban is configured to run as
+# a normal user, the configuration must be done by some other means
+# (e.g. using static firewall configuration with the
+# iptables-persistent package).
+# 
+# Explanation of the rule below:
+#    Check if any packets coming from an IP on the f2b-<name>
+#    list have been seen in the last 3600 seconds. If yes, update the
+#    timestamp for this IP and drop the packet. If not, let the packet
+#    through.
+#
+#    Fail2ban inserts blacklisted hosts into the f2b-<name> list
+#    and removes them from the list after some time, according to its
+#    own rules. The 3600 second timeout is independent and acts as a
+#    safeguard in case the fail2ban process dies unexpectedly. The
+#    shorter of the two timeouts actually matters.
