In almost every consumer grade routers i've seen UPnP was there, but turned of by default.....
I just browsed around on the pfSense site, and as i have read into the forum "flash image is only provided as convenience"....
Since i run m0n0 on a Via C3 530Mhz thin client and a CF card (using CF/IDE adapter) flash image is a must have for me, and i do not want to run a stripped down version.... I want it all or not !
I have some programming skills but I would not even know where to start to add this to m0n0......
