1. NAT (от англ. Network Address Translation — «преобразование сетевых адресов») — это механизм в сетях TCP/IP, позволяющий преобразовывать IP-адреса транзитных пакетов.

Преобразование адресов методом NAT может производиться почти любым маршрутизирующим устройством (маршрутизатором, сервером доступа, межсетевым экраном). Наиболее популярным является SNAT, суть механизма которого состоит в замене адреса источника (англ. source) при прохождении пакета в одну сторону и обратной замене адреса назначения (англ. destination) в ответном пакете. Наряду с адресами источник/назначение могут также заменяться номера портов источника и назначения.

Принимая пакет от локального компьютера, роутер смотрит на IP-адрес назначения. Если это локальный адрес, то пакет пересылается другому локальному компьютеру. Если нет, то пакет надо переслать наружу в интернет. Но ведь обратным адресом в пакете указан локальный адрес компьютера, который из интернета будет недоступен. Поэтому роутер «на лету» производит трансляцию IP-адреса и порта и запоминает эту трансляцию у себя во временной таблице. Через некоторое время после того, как клиент и сервер закончат обмениваться пакетами, роутер сотрет у себя в таблице запись о n-ом порте за сроком давности.
