Option 82 : Disabled
Response validation : Disabled
Option 82 handle policy : append
Remote ID : mac

I have changes almost every setting but I cannot seem to ge tit to work.
Is ther esomething else that should be in place here for it to work?
Is there any debugging I can do to determine what is going wrong?
