Example of Basic Configuration Output

Step 12 Change to interface command mode. For example:

router(config)# interface ethernet0 router(config-if)#

Step 13 Enter the IP address and subnet mask for the LAN. For example: router(config-if)#ip address 192.168.1.1 255.255.255.0

Step 14 Enable Network Address Translation (NAT) on your LAN. The inside network address is not directly routed to the Internet but is subject to translation to a routable address outside the LAN.

router(config-if)# ip nat inside

Step 15 Set the BRI interface IP address. In the following example, IP addresses are dynamically assigned:

router(config-if)# interface bri0 router(config-if)# ip address negotiated

Step 16 Enable PPP.

router(config-if)# encapsulation ppp Step 17 Configure CHAP authentication.

router(config-if)#ppp authentication chap

Step 18 Configure a valid Internet address to which the inside network address will be translated. router(config-if)# ip nat outside

Step 19 Define the router hostname and password to authenticate. For example:

router(config-if)# ppp chap hostname 802 router(config-if)# ppp chap password cisco

Step 20 Exit to global configuration mode. Add default route and interface. For example:

router(config-if)# exit

router(config)# ip route 0.0.0.0 0.0.0.0 bri0

Step 21 End configuration mode.

router(config)# end router#

Step 22 In user mode, set global NAT commands. In the following example, all inside network addresses assigned to interface BRI0 are configured for translation, and the access list that contains the inside network addresses is defined.

router# ip nat inside source list 1 interface bri0 overload

router# access-list1 permit 192.168.1.0 0.0.0.255

Step 23 Save your configuration.

router# copy running-config startup-config
