Hi Will,
This question seems tricky,Is there any DLSW or IPX configuration in your
practice lab? I think you should think about these topics..and use some
"deny filters" in your BRI interfaces, not only in the dialer-list.If you
use permit IP, you can filter IPX but what about DLSW? Because it is using
tcp port 2065 and IP is including tcp 2065.
Any idea??
Abidin.

Subject: IP Expert ISDN Question
Dear all CCIE and 2b
I have come across this question in my test lab which say that:
"Make sure only IP is allowed when the ISDN line is up".
What does it mean?
The Bri0 interface only have ip address and there are no any routing
protocol running on it. Should I use any access list to allow only IP or
what should I do?
Or use an access list 200 to permit 0707 (07 ---> IP) only?
Please help me to clear my "congested" mind.
Thanks.
Best regards,
William
