i have a 5505 running 8.4, and my ISP is giving me a /64 IPv6 Prefix. Basically, I have a subnet between my ASA and my ISP's box which is my outside, running into a private subnet (192.168.0.0), as most of ISP does.
I have my ASA behind, and i'd like to turn on IPv6 for my inside hosts, but the problem is that I can't modify the routing on y ISP's side, and thus it will assume all host are directly connected in my outside. Thus, I would need some kind of Neighbor Discovery Proxy on the Outside of the ASA. Is there such feature ?
If you have any other idea, then feel free to share
