If monowall people is so closely bind to the WAN, LAN, OPT1 model, there 
is very few to discuss. Then it's time to start a m1n1 project, with 
wider views.

But if you consider that this firewall is very used because of the 
speed, and because of the speed is used in a lot of big configurations, 
where people has:

    * Direction VLAN
    * Marketing VLAN
    * IT VLAN
    * Meetings VLAN
    * Accounting VLAN
    * Wi-Fi VLAN
    * Reception VLAN
    * Remote Office 1 Exchange VLAN (Radio connection)
    * Remote Office 2 Exchange VLAN (HDSL connection)
    * Server VLAN
    * Internet VLAN

than you may see that

    * ONE  outbound rule written in the server VLAN eliminates the need
      for other 11 rules which should be written in each of the other
    * ONE outbound rule written in the Internet VLAN solves the same problem
    * TWO deny inbound and outbound rules on Wi-Fi eliminates ANY
      security issues about Wi-Fi

With a few inbound and outbound rules you solve any problem. All in one 
page, for a complex situation.
Try to make the same only with inbounds rules!!!!!!

I hope monowall is ready to make the step to be a more complete firewall.
