I am sorry but the ifconfig i posted to the bug report obscured the real
ipv6 addresses, here is the output from the ifconfig gif0:

--> ifconfig gif0
gif0: flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST> mtu 1280
        tunnel inet 68.237.254.104 --> 64.86.88.116
        inet6 2001:5c0:8fff:fffe::d61 --> 2001:5c0:8fff:fffe::d60
prefixlen 128
        inet6 fe80::220:edff:fe88:e0d7%gif0 prefixlen 64 scopeid 0x8

I have not installed the freenet6 tspc client manually but rather use
the FreeBSD port from /usr/ports/net/freenet6 and i don't think it has
been recently modified by the port author. Nor my configuration changed
as i've used the tscp client since FreeBSD 5.0. I started seening
problems with tspc not being started on boot about 2 months ago when i
updated to STABLE_6 branch (which has changes to the boot process). This
works on FreeBSD 6.0-RELEASE though.

I think the problem is evident now, these are verbose results from the
boot process, it seems like the freenet6 rc script is started either too
early or the ppp is started too late and then the tspc cannot find the
nameservers defined in tspc.conf and it fails to start on boot. Here are
the verbose entries from the logs:

If there's anything else i could do to help in debugging this please let
me know, i hope its not too late to have this fixed for 6.1 release.
