      parameters only after the protocol match etc.
    * referenced variables must exist
    * list item negation is not possible

    * tables and chains must be specified first
  - deprecated syntax:
    * using a policy as default target for a rule
    * target MASQ, use MASQUERADE instead
    * lower-case built-in chain names and targets
    * lists must be specified with parantheses and no commas (old syntax
      is deprecated, but still supported)
    * variables declared with 'set' and referenced with '%NAME'
    * many shortcuts like 'mac' and 'tosrc'
    * shortcuts without the dash like 'tcpflags' ('tcp-flags')
    * "option iptables"; only iptables is supported
    * source/destination
    * option automod
    * policy within a rule declaration
