No more broken connections ... But there I've seen another problem. After booting I start a script in /usr/local/etc/rc.d/ppp.sh . After the script is invoked, ppp is waiting for tcp-connections. This works. But the first time ppp opens a connection, nothing works. I'm not able to ping, I can't see another host. Traceroute fails. My modem sends 100 and more requests but get's nothing. The route is set correctly, ifconfig does not show anything special. I see packets going out, but none of them returning. :-( I can only see thousands and more of these NS Requests ... 14:43:43.945817 194.235.47.66.53 > 194.235.47.66.53: 56907+ A? localhost.

If I remove the forwarding nameserver in named.boot, these problems did not happen, or a least only for 10 seconds. Why that ??? The second or third time ppp is invoked, it works as it should. From this time on it works great and ppp follows also my filter-options. Here's my ppp.log from the first time I connect ...
