I am attempting to stop netbios and other traffic that initiate an isdn call from entering an ethernet interface on a cisco 801 router. When traffic hits the ethernet interface, the isdn line comes up(about every 5 minutes) and makes a call. And you know what that means. Sometimes it stops traffic from placing a call, but most of the time it doesn't. I have sniffed the traffic and it is primarily microsoft stuff that brings up the line and makes the call. I have tried multiple configs, but no seem to stop netbios completly. If anyone has suggestions, I would greatly appreciate them. I have a snip of the access-list below. I have also tried using the udp and tcp port numbers, but I get the same results. Thanks.
