Proxy_NDP and whole Subnet
« on: March 09, 2012, 07:00:04 AM »

Hi, all!

I've got a working tunnel with my server using 3 /72-subnets.
It works fine, but I have a problem: I must configure a proxy for every IP in my subnet...

I tried this on my server:

/sbin/ip -6 neigh add proxy 2001:1608:10:47:1000::1 dev eth0
/sbin/ip -6 neigh add proxy 2001:1608:10:47:1000::2 dev eth0
/sbin/ip -6 route add 2001:1608:10:47:1100::/72 via 2001:1608:10:47:1000::2 dev ipv6tun metric 1

hoping to get the traffic for the whole subnet (2001:1608:10:47:1100::/72 on my PC and my wife's PC) through my tunnel endpoint, but it does not work. I can't reach any host in the subnet 2001:1608:10:47:1100::/72 from other than my server...

If I give this command:

/sbin/ip -6 neigh add proxy <IP in my subnet> dev eth0

on my server, then it works...

So, how can I say the internet "all IPs of my subnet can you reach using my tunnel", and then just proxying my tunnel endpoints?

Thanks a lot!
