can you ping 2001:6f8:306::1 from 2001:6f8:306::11, then can you ping 2001:6f8:202:202::2. if not look at ip -6 r g 2001:6f8:202:202::2 see what is says try the reverse ping 2001:6f8:306::11 from 2001:6f8:306::1. Also have you turned on ipv6 forwarding ? sudo sysctl -a | grep ipv6 also maybe check ip6tables -nvL > > Now what is strange is if I ping6 nadia from kaname (or the opposite) at > the same time kaname pings www.ipv6.org all is working fine! > > If I stop the ping between nadia and kaname, kaname still continues to > receive replies from www.ipv6.org for a few seconds and then it stops > working. > > I presume this has something to do with the neighbor > solicitation/advertisement feature, but I don't know how to solve the > problem. > > Please let me know if you need additional informations. > > Any help would be greatly appreciated. > -- > strawks <[EMAIL PROTECTED]>
