Hi, I have been looking for an IOS version which does include a Firewall Feature Set, (known as Cisco IOS Firewall) for a Cisco 2801 router, but I can't find it. All what I find is a release named "IOS Advanced Security".
Does this "IOS Advanced Security" has the firewall features that Cisco IOS Firewall did?
