Good morning ;-)
I am not block all outgoing traffic from the local box just the dns-requests coming from the box itself - I have bind8 running on the machine.
All other blocking-rules are in the forward chain ... so if I run win ther won't be a connection established all 3 min. :-) ... default policy (from the linux-box) for outgoing connections is allow (accept) ...

Yes, that's it.
I don't know why... all possible outgoing traffic has been blocked ( for
testing ) but he will not hangup... :-(
That MAY be your problem.
I'm NOT using ISDN, but on my dial-up modem connection, when I hit CTRL-C, to kill wvdial, there are a few packets sent out from my modem, to cleanly terminate the dial-in connection.
Sometimes my dial-in connection will stay live, if I do NOT finish wvdial in the correct manner. eg CTRL-Z instead of CTRL-C.
If you are blocking ALL outgoing packets, this may be why the connection stays open - because the signal to terminate your ISDN connection is not reaching your ISDN service provider.
Here's my 56K modem start sequence:
topaz:/home/keith # wvdial --> WvDial: Internet dialer version 1.42 --> Initializing modem. --> Sending: AT&F0&C1 AT&F0&C1 OK --> Modem initialized. --> Sending: ATDT1470 0808 9933 030 --> Waiting for carrier. ATDT1470 0808 9933 030 CONNECT 38400 --> Carrier detected.

Press Ctrl-C to disconnect
[1]+ Stopped wvdial
I've just checked this by hitting CTRL-Z.
My line is still live!
I now have to turn my modem OFF to break the connection.
Now, trying to redial I get:
topaz:/home/keith # wvdial --> WvDial: Internet dialer version 1.42 --> Cannot open /dev/ttyS1: Device or resource busy --> Cannot open /dev/ttyS1: Device or resource busy --> Cannot open /dev/ttyS1: Device or resource busy
Because the wvdial script was not stopped correctly.
Now I kill the bash shell in KDE to remove the device lock, and free up the modem!
