Extended Access Lists Configuration With Packet Tracer

In this lesson we will focus on Extended Access Lists Configuration with Cisco Packet Tracer. We will use the below topology for our packet tracer configuration.

Extended acl with packet tracer

You can DOWNLOAD the Cisco Packet Tracer example with .pkt format at the End of This Lesson.

Like Standard ACL configuration example, we will use one router, one destination server and 3 PCS in common. The switches in the topology will onlu used for port need.

Extended ACLs are a little complex if we compare with Standard ACLs. With Extended ACLs, we can restrict or allow specific things like destination, protocol or port.

In this Extended ACL example, we will allow/deny ICMP protocol through the server. As you know, ICMP is ping protocol. Here, PC0 and PC1 will be allowed and PC2 will be denied.

Extended Access-List Configuration

Let’s start to configure router for our Extended ACL.

For Extended ACLs, we can use Extended Access-List Number range 100 to 199. Here, we will use 100.

Router # configure terminal
Router (config)# ip access-list extended 100 
Router (config-ext-nacl)# permit  icmp host
Router (config-ext-nacl)# deny  icmp host host host-unreachable
Router (config-ext-nacl)# end
Router # copy run start
