Hi,
I am using freebsd 4.11 and trying to setup ipv6 in ipv6 tunnels.
I have the following testbed
4 machines connected in line:
M1-----------M2--------FreeBSD-------M3
c::1---c::2 | b::2----b::1 | a::1---a::2
I want to create a tunnel between FreeBSD (b::1) and M2 (b::2)
Here is my configuration on the FreeBSD machine:
em0 : a::1/64
em1 b::1/64
I do the folllowing to setup the tunnel:
ifconfig gif0 create
ifconfig gif0 tunnel b::1 b::2
ifconfig gif0 d::1/64
route add -inet6 -host c::1 -interface gif0
I am not sure about what is the gif0 address d::1/64 used for.
the problem is: when i ping or send any traffic from a::2 to c::1,
the FreeBSD machine adds an ipv6 header with b::1 as source, b::2 as destination, but with hop count limit=0
Is my configuration ok?
Thanks a lot,
Julien
