It seems that it might be easier to config if you allow only what you really need and let the implied deny statement at the end of the access list work better and smarter for you. If that can't be done, being more specific is needed to look into this further. What kind of "Microsoft stuff" are you referring to? Rik -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] Sent: Wednesday, May 17, 2000 12:11 PM To: [EMAIL PROTECTED] Subject: netbios and other call placing traffic 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.
