/64! That is a lot of addresses. I like it, but all is not well. Some devices are dual stack and ready to talk. But some devices are not dual stack and they need some help. NAT for ipv4 has been around a long time, and iptables NAT in the linux kernel has served me well. Now I need NVT (Network Version Translation).
Is there some iptables mangle command or NVT command that will take 192.168.1.1 and send it as 2607::192:168:1:1 and receive 2607::192:168:1:1 and translate to 192.168.1.1? It could also be stated as 10.1.1.1 NVT 2607::10:1:1:1 or 10.10.10.1<=>2607::10:10:10:1
Then iptables can be configured to have some addresses allowed and some stateful (default would be stateful).
What about a single device inside — is there an ethernet dongle that will do 1 to 1 NVT? Would it have to be powered by POE or usb?
