Review Notes, v. 3.1 1.1.1 Private addressing 1.1.2 Major NAT and PAT features Dynamic NAT is designed to map a private IP address to a public address. Any IP address from a pool of public IP addresses is assigned to a network host. Overloading, or Port Address Translation (PAT), maps multiple private IP addresses to a single public IP address. Multiple addresses can be mapped to a single address because each private address is tracked by a port number. 1.1.3 Configuring NAT and PAT 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. 1.1.4 Configuring DHCP - Typically, a DHCP server will be configured to assign much more than an IP address. Other IP configuration values such as the default gateway can be set from the DHCP configuration mode. Using the default-router command sets the default gateway. - A default router must be defined for clients 2.1.1 WAN devices - For digital lines, a
