-# 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
