NAT are supported m Basic NAT m Network Address Port Translation NAPT NOTE Basic NAT and NAPT cannot be enabled at the same time Basic NAT allows hosts in a private network to transparently access the external network by using a block of public addresses Static mapping enables access to selected local hosts from the outside Basic NAT is often used in a large organization with a large network setup for internal use and the need for occasional external access Basic NAT provides a one to one mapping by translating a range of assigned public IP addresses to a similar sized pool of private addresses typically from the 10 x x x address space Each local host currently communicating with a external host appears to have an unique IP address Up to 256 IP addresses can be allocated for use with Basic NAT Network Address Port Translation NAPT 3 6 NAPT allows multiple clients in a local network to simultaneously access remote networks using a single IP address This benefits telecommuters and SOHO Small Office Home Office users that have multiple clients in an office running TCP UDP applications NAPT is sometimes referred to as PAT Port Address Translation NAPT provides a many to one mapping and uses one public address to interface numerous private users to an external network All hosts on the global side view all hosts on the local side as one Internet host The local hosts continue to use their corporate or private addresses
