Subject: proxy ARP/IPv6
Hi,
I was trying to setup up a proxy arp kind of thing for IPv6 host
here is the scenario
interface: eth0 interface: tap0
------------ via TUN/TAP -------------
|ipv6-1 | <-----------> | | ------> [[[[ internet6]]]]]
| | | maryo |
|---------- |___________|
ipv6-1 runs runs usagi 16sept02
vanilla linux 2.4.19
maryo can ping6 outside ipv6 hosts perfectly.
maryo has following interface(s):
eth0, tap0,ngc-maryo ...
nag-maryo(tunnel mode sit) : assigned 3ffe:8271:a026:feee::1
assigned 3ffe:8271:a026:feee::/64 route.
eth0(ethernet) : assigned 3ffe:8271:a026:feee::2
tap0(TUN/TAP) : assigned 3ffe:8271:a026:feee::3
assigned a route of host 3ffe:8271:a026:feee::4
(all these ip addresses can be directly reached by outside perfectly).
Now the ipv6-1 host has following interfaces
eth0 (TUN/TAP actually to tap0) : assigned 3ffe:8271:a026:feee::4
assigned route 3ffe:8271:a026:feee::/64
Now from the host ipv6-1 i can ping6 3ffe:8271:a026:feee::3 fine
but NOT 3ffe:8271:a026:feee::1 ? i assume , i need to setup some sort of
relay for neighhour discovery messages for 3ffe:8271:a026:feee
i tried ip -6 neigh add proxy 3ffe:8271:a026:feee::4 dev ngc-maryo / eth0
both, but don't seems to work.
Please help.
Thanks
