I have a very elementary ACL question, but for the life of me I can not get it to work. My home lab scenario is this;
I have a specific computer (SERVER A) on my 192.168.20.x network, and I do not want it to be able to access the Internet, which is accessible through my consumer Netgear router at 192.168.0.1. In between the 192.168.20.x network and the 192.168.0.x network is a Cisco 2851. The 2851 has the default static route set to 192.168.0.1, the address of the Netgear router. However, both networks need to be able to communicate with the server internally. Below is a sketch of the network.
SERVER A -------- (INT GI0/1 ------INT GI0/0) ----------------(NETGEAR ROUTER 192.168.0.1)-----------INTERNET
deny tcp host 192.168.20.20 host 192.168.0.1
deny ip host 192.168.20.20 host 192.168.0.1
permit ip any any
I figured I probably needed to apply it to the gi0/0 interface since the routing process would be sending it out that interface, however neither direction is blocking the attempt to access the Internet.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
