I noticed that my website filtering had stopped. I read some of the other folks who had the same problem. It used to work, and to be honest, the extended list was one of the reasons I bought this piece of junk. Well, what had changed? Ah! Turn "Enable DNS Relay" back on! Now web filtering works, but now my router will lock up soon, I'm sure. I've not had lock up issues since I turned that off.
