+# RULE SYNTAX:
+#
+# forward:<match>:<target>[:<port>]
+# - forwards all packets matched by <match> to <target>,
+# optionally changing the port to <port>
+#
+# accept:<match>
+# - accepts all traffic matched by <match>
+#
+# drop:<match>
+# - drops all traffic matched by <match>
+#
+#
+# MATCHING OPTIONS:
+#
+# src=<ip>
+# - match the source ip <ip>
+#
+# dest=<ip>
+# - match the destination ip <ip>
+#
+# proto=<proto>
+# - match the protocol by name or number
+#
+# sport=<port(s)>
+# - match the source port(s), see below for syntax
+#
+# dport=<port(s)>
+# - match the destination port(s), see below for syntax
+#
+#
+#
+# PORT SYNTAX:
+#
+# You can enter an arbitrary list of ports and port ranges in the following format:
+# - 22,53,993,1000-1024
+#
+# If you don't set the protocol to tcp or udp, it will apply to both
+#
+#
+#
+# EXAMPLES:
+#
+# drop:dport=22 src=1.3.3.7
+# accept:proto=tcp dport=22
+# forward:dport=60168:192.168.1.2:60169
