I have a real simple newbie question that I do not expect a detailed answer for. All the information I have seen on configuring routers for IPv6 shows both the WAN and LAN sides as using IPv6. Are there routers that will allow you to have a single IPV6 (no IPv4) address on the WAN side and conventional IPv4 private addresses on the LAN side? I suspect I am not seeing anything about such a configuration because there is very good technical reason why that is not possible. If that is the case, I will continue to look for the reason. All I need to know is if that is indeed the case. Thanks
