Why is it when I apply an access list thet enables individual users to access ports(like port 80), why does the Ubr crawl and come to a complete stop in proccessing modems information? The network temporarily goes down until the access list has applied all of its rights(permits and denys). As soon as the list is complete and I save its alterations, network comes back up. What is up with that? I’m going to also consult with Cisco.
