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????
the difference between normal access-list and IOS Firewall is that IOS FW will dynamically punch in holes into your ACL, whereas, in normal ACL, you have to do it manually, and if for example, you have a long list of IPs with various different ports to permit/deny, then your ACL is huge and every packet arriving has to go through the ACL. So, the IOS FW will punch in holes as and when required and only for that particular session, if the session logs out, the hole is removed and ACL is shorter again.
