Hi, at the moment I have a Cisco 1605R ios v12.0.4 without firewall. So I have to use access list. What difference would it make if I use an IOS with the firewall option??? What can a ios with firewall do that the access list can't do???
What is the difference between an ios with firewall and a normal access list.
Can a cisco router authenticate username and password wan connections instead of permitting ip address????
Access-lists don't keep state information by default unless using the established keyword. The firewall feature set is a more feature rich statefull firewall. It acts like the pix in that it allows outbound and creates inbounds based on that info. An access-list is more of a static, less flexible, less secure solution that takes more work to maintain.
