Hello,

Let me follow the BUGS-REPORTING procedure :

[1.] Ooops following the 5th or 6th IPv6 ping received thru a tap
     interface (using VTun).
[2.] I'm using VTun to link two machines, thus having IPv4 and IPv6 set
     up on two boxes. I also have a two sit interfaces as the machine
     is also connected to an IPv6 network. I've activated IPv6 forwarding.
     From the second machine (not routing anything) at the end of the
     VTun/tap tunnel, I start a ping6 command either directly to the end
     of the tunnel or involving routing action.
     Following receipt of the 5th or 6th IPv6 packet, the machine crashes.
     When using only IPv4 traffic, no problem occurs.
[3.] Networking - IPv6
