Hi all,

I've a machine running FreeBSD 4.1 and I want to use it to connect to the 
6bone using 6to4 encapsulation. However, I've yet to succeed and am 
encountering problems or sorts also. I'm using the KAME stack that comes 
with the FreeBSD 4.1 distribution.

The following is the configuration that I have in my /etc/rc.conf file...

ipv6_enable="YES"
ipv6_gateway_enable="YES"
ipv6_router_enable="NO"
ipv6_network_interfaces="lo0 xl0"
ipv6_prefix_xl0="2002:8984:a376:0"
ipv6_static_route="default"
ipv6_route_default="default 6to4.ipv6.microsoft.com"
stf_interface_ipv4addr="137.132.163.118"

I've also recompiled my kernel with the "pseudo-device stf 1" option.

Now the problem...

After all the above has been done, rebooted the machine and when I tried to 
"ping6 6to4.ipv6.microsoft.com" or any other 6to4 or 6bone address, I 
couldn't get a reply at all. It just waits indefinitely for a reply.

When I do a ifconfig stf0, it showed

stf0: flags=1<UP> mtu 1280
inet6 2002:8984:a376::1 prefixlen 16

stf0 is only UP but not RUNNING and it also does not have a link local 
address attached to it. Is this what is causing the problem that I'm facing?

I've been trying to solve this problem for a week without any progress and 
its getting really frustrating.
Please advise. Thanks.
