I'm needing a simple gigabit wireless router. I don't need more than 4 lan ports. I prefer wireless N, but would settle for a super G. The main feature I'm looking for though is one with multiple website url blocking. I would like one that will block 50 or more specific url addresses. This doesn't have to be per client. The cisco M20 valet shows that it has parental controls with url blocking, but I can't find any specifications on how many sites I can block. Any suggestions anyone?
