Hi, since I've set up my tunnel manually for the first few days I now tried to get it work automatically after reboot. First copied the config from the FAQ to /etc/network/interfaces. First persistent problem is I have to add "metric 128" to the route add default line because the default seems to be 1024. Although after the clean reboot this route is the only "default route" for ::/0 (there are local routes for fe80::/64, ff0::/8 etc), it won't work with metric 1024. No ping, nothing until I change the metric to something less than 256 which is the metric for all local routes. Doesn't make sense to me??? My second problem now is that "ifdown" doesn't work for the tunnel device. 'ifdown sixxs' calls 'ip tunnel del dev sixxs' and this ip-command hangs up using 99.9% cpu. The process even cannot be killed with SIGKILL:-/ On the syslog console the following line shows up: kernel: unregister_netdevice: waiting for sixxs to become free. usage count =1 This message repeats after some time again and again. When trying to reboot (without calling ifdown manually) the shutdown hangs at "Deconfiguring network interfaces..." I didn't wait longer than some minutes and then just hit the reset button. I also tried a "pre-down ip route del..." line in /etc/network/interfaces which didn't help. Any ideas? Regards, Wolfgang
