Camping in belgium sites?

Sorry if i sound ignorant, but i dont know much about the country. I know i'd like to visit Gent but other than the tourist traps of Brugge/Brussels/Antwerp etc i really dont know much about the country. I have about 4 days before i move on and have booked the 1st night in Gent. I would love suggestions on camping spots, close by to a small sized town but relatively off the beaten track? Or would Luxembourg be a better bet? There arent many independent websites out there to point me in the right direction, they all have a interest in me bookin my stopover with them..
