�Hola!
I'm trying to setup an IPv6-over-IPv4 tunnel.
I do in box-1:
ip tunnel add test mode sit remote <box-2-ipv4> local <box-1-ipv4>
ip link set test up
ip addr add <prefix::1>/64 dev test
ip ro add <prefix::2>/64 dev test
In box-2:
ip tunnel add test mode sit remote <box-1-ipv4> local <box-2-ipv4>
ip link set test up
ip addr add <prefix::2>/64 dev test
ip ro add <prefix::1>/64 dev test
Then i do ping from box-1. I see the packets coming to box-2 but box-2 doesn't
answer.
tcpdump trace:
19:09:04.162253 <box-1-ipv4> > <box-2-ipv4>: v6-in-v4
<prefix::1> > <prefix::2> icmpv6: echo request (DF)
(lots of them)
Similar thing happens when configuring my tunnel to the 6bone. The other end
is well configured so i see my echo requests going and my uplink's echo
replys, but the box doesn't recognize the replys.
I remember from the old times of tunneling that there were 2 modules, the
encapsulator and the decapsulator. It seems that the decapsulator isn't
working. What did i forgot to do to activate it?
TIA,
HoraPe
