I've been thinking a little more about this. Is the MAN part of your local subnet? IE, if the pfSense WAN interface was on 24.0.0.0/8 is the MAN the same subnet, or is it just something you have to go through? I think I can make an "easy" change for local subnet on the WAN side of the firewall.
Never mind...I started to implement this and realized it won't work w/out more queues which I don't want to add right now ;)
