Note that packets that do not match this address translation rule will be transmitted between these two interfaces unchanged. If you want to transmit only translated packets between these two interfaces, you need to configure the appropriate ACL.Video 22.01.A multimedia demonstration of configuring static NAT on a router is included in the companion digital resource to this book.Configuring Dynamic NAT When configuring dynamic NAT, you need to configure three things: which internal addresses are to be converted; which global addresses are to be used for dynamic conversion; and which interfaces are to participate in the conversion. To specify which internal devices' source addresses are to be converted, use the following command. Router(config)# ip nat inside source list standard_IP_ACL_name_or_# pool NAT_pool_nameIn the command ip nat inside source list, you must specify a standard IP ACL, which specifies which internal source addresses are to be converted: all addresses matching the permit statement are converted, and none matching the deny statement or the implicit deny statement are converted. Next is the name of the address pool: it specifies the address pool to be used, which contains the global source IP addresses.To create an internal global source IP address pool, use the following command. Router(config)# ip nat pool NAT_pool_name beginning_inside_global_IP_address ending_inside_global_IP_address netmask subnet_mask_of_ addressesThe address pool name is used to specify the address to be translated to in the command ip nat inside source list. Next, the starting and ending addresses that the address pool contains, followed by the subnet mask of the address. The last item to configure after configuring the address pool is to specify which interfaces are internal and which are external. To do this, use the interface subconfiguration commands ip nat inside and ip nat outsideo discussed earlier in this chapterThe command ip nat inside source list specifies which internal addresses are to be dynamically translated. Do not forget that packets are converted only if they match a permit statement in an ACL: no conversion is performed for packets that match a deny statement or an implicit deny statement. The command ip nat pool specifies which global addresses will be used when performing dynamic conversion of local addresses
