Default Re: Knowledge Points

Knowledge Points:

To configure the NAT, taking the following steps:

1. Define the internal and external network for the NAT.
(config-if)#ip nat inside Specify the internal interface.
(config-if)#ip nat outside Specify the external interface.

2. Configuring the source IP address to be translated.

Static mapping
(config)#ip nat inside source static Local_ip _addr global_ip_addr

Dynamic mapping
(config)#ip nat inside source [ list { 1-99 } | route-map ] pool pool_name overload

3. Configuring the dynamic address pool for overload NAT
(config)#ip nat pool netbrain begin_IP end_IP netmask mask
