I am reading a Cisco Press book on Securing Perimiter Routers.
"Cisco Router Firewall Security" R.Deal @2005
It gives an example of Auto Secure with a couple of humongous ACL's.
One for example is for all Private Ip Source Addresses RFC 1918 blocked from the outside. Another is an IANA list. When I run auto secure on my new 2811 with advanced IP services it doesn not generate these long long ACL's. What has happened and is Auto Secure really a valid tool today???
