What is Access Control List (ACL) - Configure ACL

This lab is about Access Control List (ACL). In this tutorial we will discuss about Access Control List (ACL) Implementation on Cisco Packet Tracer, in last tutorial we discuss about Concept of IoT (Internet of thing)



Access Control List (ACL)




What is Access control list? Access control list contains on Access control Entries (ACE). Each ACE is an ACL identifies a trustee and specifies the Access right allowed, denied or audited for that trustee.




There we will discuss two type of ACL which is used to create Access list

  • Standard Access control list (SACL)

Standard ACL is used to create Access list in which we can permit or deny a network or a host and Standard ACL is Closest to Destination. The Standard ACL range is 1-99.

  • Extended Access control list (EACL)

Extended Access control list is used to create Access list, in which we can permit or deny a protocol and IP. Extended ACL is Closest to Source, Extended ACL range is 100-199.



First we will use Standard for permit only 1 PC0 and deny all other PC to communicate with other netwrok. Standard near to destination it’s mean on out side of Router0 because we are going to access 1 PC from switch0.

Now Extended we will block from network 192.168.3.0 accessing the website. Extended near to source, in this case Server s our service provider, so it’s our source.

What is Access control list (ACL)?

Resources Required for Access list (ACL) in packet tracer

  1. 2 Router (2811 Cisco)
  2. 3 switch 2960
  3. 8 PC’s (Two different network of 4,4 PC’s)
  4. 2 servers ( One DNS Server and One Web Server)

Connectivity of Resources

  • Connect Switch0 with PC’s
  1. In this network we are using 192.168.1.0 network connect all PC’s with Switch, Connect Switch f0/1, F0/2,f0/3,f0/4 with PC’s interface.
  2. if you connectivity is correct Green light blink up.
  • Connect Switch0 with Router1
  1. Connect Switch0 with Router1 with straight through cable.
  2. if you connectivity is correct Green light blink up.
  • Connect Router0 to Router1
  1. Connect Router0 with Router1 with Crossover cable, this is our second network.
  2. if you connectivity is correct Green light blink up.
  • Connect Router1 to Switch1
  1. Connect Router 1 to switch1, this is our Third network.
  2. if you connectivity is correct Green light blink up.
  • Connect Router1 with Switch 3
  1. Connect Router1 with switch3 it’s our Fourth network which contains on our server.
  2. if you connectivity is correct Green light blink up.
  • Connect switch2 with Pc’s
  1. Now connect all PC’s with switch2.
  2. if you connectivity is correct Green light blink up.
  • Connect switch 3 with DNS server
  1. Connect DNS server with Switch3 with Straight through cable.
  2. if you connectivity is correct Green light blink up.
  • Connect switch3 with Webserver
  1. Connect Web server with switch 3.
  2. if you connectivity is correct Green light blink up.
  • Creat a DHCP server in each router interface
  1. Now creat DHCP server in each router with different network.
  • Create a DNS server
  1. Create a DNS server resolve the DNS Address into name, Let 192.168.4.2 into yahoo.com
  • Trun on HTTP
  1. Trun on the HTTP service from the Web server.
  • Give IP address to all PC’s throw DHCP
  1. Go to each pc desktop and assign them Ip address with DHCP server.
