Hi,
I have a BGP tunnel setup in Sweden to tunnelbroker.net, but since a few days ago - the tunnel does not route any IPv6 packets.
I have an OpenBSD as router and has been using this configuration for years without problems.
I wonder what could be causing the problem?
This is some information about the tunnel:
# ifconfig gif0
