Freebsd is a small machine (celeron, P2, P3....) 256mb memory, 4gb or more disk 1 ethernet Software on FreeBSD ppp using bridge mode (I supose your adsl is pppoe) man ppp the adsl mode is configured to work in bridge mode and as you see , is connect in the switch together with the freebsd and the wireless bridge.... Wireless bridge..... this is the trick point of the project... After searching and testing various radios/swithes.. I deciced for the airlive 5460 ap2 http://www.airlive.com configure both ap in bridge with WDS enable and 21db of output power.... Antennas: the radios must use a small pigtail and be as near as possible to the antenna... I build the antennas using a project canantenna http://www.turnpoint.net/wireless/cantennahowto.html the two points must be visual, that is: in one point you must see the other, beware with water (lakes, flat fields...) between the points stay away from trees... put the antennas at about 6m from the soil... 10km... You must try, I have one link in 7km here... with good performance.. in severel clients (10 clients)... about 3mbits... the radios costs about 45 dollars each, the pigtail is 5dollars, the antenna is about 5 dollars each the swithes is about 20 dollars each... Should work. Hope I could help... Sergio
