+ + + + + + +

+ + Static Translation
+ To configure static inside source address translation, perform the + tasks in Figures +

and +

+ + Figure + shows the + use of static NAT translation. The router will translate packets from + host 10.1.1.2 to a source address of 192.168.1.2.

+ + Dynamic Translation
+ To configure dynamic inside source address translation, perform the + tasks in Figure + .

+ + The access list must + permit only those addresses that are to be translated. Remember that + there is an implicit “deny all” at the end of each access list. An + access list that is too permissive can lead to unpredictable results. + Cisco advises against configuring access lists referenced by NAT + commands with the + + permit any + command. Using + permit any + can result in NAT consuming too many router resources, which can cause + network problems.

+ + Figure + translates + all source addresses passing access list 1, which have source address + from 10.1.0.0/24, to an address from the pool named nat-pool1. The + pool contains addresses from 179.9.8.80/24 to 179.9.8.95/24. + +

+
+ + Note: NAT will not + translate the host 10.1.1.2, as it is not permitted for translation + by the access list.
+

+ + Overloading
+ Overloading is configured in two ways depending on how public IP + addresses have been allocated. An ISP can allocate a network only one + public IP address, and this is typically assigned to the outside + interface which connects to the ISP. Figure + shows how + to configure overloading in this situation.

+ + Another way of configuring overload is if + the ISP has given one or more public IP addresses for use as a NAT + pool. This pool can be overloaded as shown in the configuration in + Figure + + + .

+ + Figure + + + + shows an example configuration of PAT.
