ASA IPv6 NDP Proxy

Hi All,

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

ASA IPv6 NDP Proxy

Hi Baba,

Unfortunately there is no functionality like this on the ASA. The best bet would be to have the ISP fix their mask. The only way to get this to work on the ASA would be to put it into transparent (L2) mode.
