Hello, I have a VPS at a hoster where I got 3 /64 ipv6 prefixes/subnets, that are routed; one for the VPS itself - let us call this srvprefix one for the tunnel, only ::1 (server side) and ::2 (home side) are used - let us call this tunnelprefix and one for my network at home - let us call this homeprefix now I'm just in test state, a CentOS VM is the other end of the tunnel; (when the server runs well, my CentOS ZBOX will become the other end of the tunnel) at the server the eth0 device has serverprefix::1, the sit1 device has tunnelprefix::1 the routing is set with /etc/sysconfig/network-scripts/route6-sit1 tunnelprefix::2 dev sit1 homeprefix::/64 via tunnelprefix::2 dev sit1 in sysctl.conf these are set net.ipv6.conf.all.forwarding = 1 net.ipv6.conf.all.proxy_ndp = 1 now I have to do these ip -6 neigh add proxy homeprefix::1 dev eth0 ip -6 neigh add proxy homeprefix::### dev eth0 the question, can I do something to avoid these "ip -6 neigh ..."? if yes, what? and how? can the hoster do something? if yes, what? Thanks, Walter my ISP told me that he won't deploy IPv6 within the next 5 years;
