Hello,

I try to set connection to 6Bone. I've FreeBSD 4.1 with interface gif0
and static routing (inet6 default gateway 3FFE:28FF:5:FFF::1).
The remote end point have Cisco. It have configured intreface Tunnel1.
But we don't have connection, ping6 don't say anything from my place
and from remote place.

May be somebody can help me?

Thank you.
