I dont want it to be dual stacked, because I intend to force my team to perform only IPv6 related tools on the internal network. However, when performing internet activity like, reading e-mail or browsing the web, its impossible to avoid IPv4 today. I want them to be able to reach IPv4 network (internet) transparently. When DNS resolve to IPv4, they will ask the gateway (ipv6, dual stacked), who will put their v6 address in the v4 network. How can I accomplish that? Is NAT-PT the only way? If so, how can I get NAT-PT on FreeBSD? Your opinion: do you think this approach can be used for end users? I mean, someone with windows vista and teredo, is already getting IPv6 address since my FreeBSD is advertising it. However they are dual stacked. I want people to be v6-only and still can visit v4 networks transparently, without technical knowledge (say, my girlfriend who is not a geek). I guess this is a migration/education strategy, which I intend to deploy, but right now I am only studying. Will faith(4) do this for me? -- =========== Eduardo Meyer pessoal: dudu.meyer@gmail.com profissional: ddm.farmaciap@saude.gov.br
