It does not re-direct IPv6 web traffic but it does redirect all IPv4 DNS traffic to a DNS resolver that only answers with A records. Once a device has been authenticated IPv4 DNS traffic goes to a DNS server that will answer with AAAA records also. --- Bruce Curtis bruce.cur...@ndsu.edu Certified NetAnalyst II 701-231-8527 North Dakota State University
