CHAPTER 2 ■ CONFIGURING YOUR ROUTER Listing 2-7. 255 any lab-r1(config-ext-nacl)# exit lab-r1(config)# ip nat inside source list NAT-ACL interface fa4 overload lab-r1(config)# int vlan1 lab-r1(config-if)# ip nat inside lab-r1(config-if)# int fa4 lab-r1(config-if)# ip nat outside Step 1: Create and Name an Extended ACL for NAT The first step is to create an ACL that allows all of your hosts to use NAT. This is an extended ACL, not a standard ACL like you used earlier for securing your VTY lines (telnet).

These will be the static IP addresses you assign your servers, printers, switches, and routers. It’s best to define a block of addresses right from the start. That way you won’t need to reconfigure your router later to reserve (exclude) more addresses. In Listing 2-2, the first 25 IP addresses are reserved. 25. Reserve as many static IP addresses as you need, but 25 should be plenty for a small business. Step 9: Test DHCP Using a Workstation Before you continue, it’s a good idea to test your DHCP server.

I’ll go into more detail about ACLs later in this chapter. For now, let’s look at the ACL for telnet line by line in Listing 2-4. Listing 2-4. 255 lab-r1(config-std-nacl)# exit lab-r1(config)# line vty 0 4 lab-r1(config-line)# access-class VTY-ACL in CHAPTER 2 ■ CONFIGURING YOUR ROUTER Step 1: Create and Name Your ACL The first thing you do is create and name your ACL. The name “VTY-ACL” is used in Listing 2-4. You can use any name that makes sense to you, but it’s a good idea to use a name that will remind you of what the ACL is used for.
