I've seen the same = problem on=20 two freebsd 4.2 boxes. In both cases mpd-netgraph was installed on = a clean=20 box. Bringing up mpd-netgraph was fine, but as soon at a PPTP = connection=20 from a Windows98 box was established the box would crash, wait for user = input=20 for 15 seconds and then reboot. Both boxes I used has two network=20 interfaces and were using ipfilter and natd.

If the kernel routing table says that the route to the remote PPTP machine is via the PPTP link, then we get an infinite loop and the kernel panics. There should probably be infinite loop detection support in netgraph, or maybe mpd could try to watch for this condition, etc. http://www.FreeBSD.org/cgi/query-pr.cgi?pr=25029 >Unformatted:
