Yes, 4096 VLANs is a good point. 10/8 gives 64k /24 networks. I would not use that if the original networks actually are in 10/8 however, to avoid all the potential problems and confusion of mixing the original addresses with the mapped ones. Since the original poster wrote "numerous" and did not specify exact addressing setup, I wanted to at least mention the scalability issue. Thanks! :) //Peter
