Nonetheless, NAT can introduce complications in communication between hosts.     * NAT(Network Address Translation) is most commonly used by broadband routers. NAT allows the router to assign non-publically routable IP addresses to the computers on the network.
Disadvantages of NAT. â¢ NAT (Network Address Translation) is a processor and memory resource consuming technology, since NAT (Network Address Translation) need to translate IPv4 addresses for all incoming and outgoing IPv4 datagrams and to keep the translation details in memory. NAT (Network Address Translation) may cause delay in IPv4 communication. â¢ NAT (Network Address Translation) cause loss of end-device to end-device IP traceability. â¢ Some technologies and network applications will not function as expected in a NAT (Network Address Translation) configured network.
