topic ASA IPv6 NDP Proxy in Network Security https://community.cisco.com/t5/network-security/asa-ipv6-ndp-proxy/m-p/1827422#M492354 <P>Hi All,</P><P>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.<BR />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 ?</P><P>If you have any other idea, then feel free to share <SPAN __jive_emoticon_name="happy" __jive_macro_name="emoticon" class="jive_macro jive_emote" src="https://community.cisco.com/4.5.4/images/emoticons/happy.gif"></SPAN></P> Mon, 11 Mar 2019 21:55:39 GMT babanonyme 2019-03-11T21:55:39Z ASA IPv6 NDP Proxy https://community.cisco.com/t5/network-security/asa-ipv6-ndp-proxy/m-p/1827422#M492354 <P>Hi All,</P><P>i have a 5505 running 8.4, and my ISP is giving me a /64 IPv6 Prefix.

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.</P><P></P><P>-Mike</P></BODY></HTML> Wed, 30 Nov 2011 16:22:37 GMT https://community.cisco.com/t5/network-security/asa-ipv6-ndp-proxy/m-p/1827423#M492357 mirober2 2011-11-30T16:22:37Z
