>Description:
ISDN dial-up network connections seem to hang immediately after dial-up
when connecting to a site that gives us a dynamic IP address.
Enabling debug logging on the isp[n] interface shows:

Although IPv6 is disabled, netstat output looks screwed up like this, but ONLY
WHEN A CONNECTION IS OPEN (as soon as connection is closed, it looks normal
again).

>How-To-Repeat:
Open any dial-up connection using isdn4bsd and the isp[n] devices
to see the wierd netstat output. Open any dial-up connection with
dynamic addressing shows that it doesn't work. Open a dial-up
connection with a static IP address for my site shows that it's
working.
