Dear Fellow Members,<br><br>I have a question concerning ACL's or (access control lists) on Cisco Routers. I have a friend whose company is using pure ACL's only, with no Firewall anywhere on their corporate network. One Cisco router having an ACL list spanning over 5 pages (heavy load).<br><br>I want to suggest to him for the company to invest in a firewall, namely FW1. Can anyone here explain to me in further detail a good arguing point for why ACL's should not be so heavily relied on, and common ways of evading them? <br><br>Thanks in Advance.<br>Eric
