Configuring Traditional NAT Dynamic Inside Address Translation

Traditional NAT Dynamic Configuration describes how to configure traditional NAT for a dynamic configuration.

Traditional NAT Dynamic Configuration

Step	Task	Command(s)
1	Enable NAT, in interface configuration mode, on both the inside and outside interfaces.	ip \| ipv6 nat {inside \| outside}
1.	Define, in global configuration mode, an IPv4 or IPv6 access-list of permits for all inside addresses to be used by this dynamic translation.	ip \| ipv6 access-list list-number {deny \| permit} source
2.	Define, in global configuration mode, a NAT address pool for all IPv4 or IPv6 outside addresses to be used by this dynamic translation.	ip nat pool name start-ip-address end-ip-address [netmask netmask \| prefix-length prefix-length] ipv6 nat pool name start-ip-address/prefix-length count count
2	Enable, in global configuration mode, dynamic translation of inside source addresses. Specify the overload option for NAPT translations. Do not specify a pool when configuring a dynamic NAT firewall list rule.	ip \| ipv6 nat inside source list access-list [pool pool-name] [interface interface-name] [overloaded] [inside-vrf vrf-name] [fullcone acl \| restricted-cone acl \| port-restricted-cone acl]
