As already mentioned earlier, the NAT uses the TCP/IP protocol feature of using the IP packet with TCP or UDP ports with the modified IP header field for the translation purpose. So the header of the IP packet will carry the following fields: Source address– The IP address of the initiating host PC like

Network Address Translation (NAT) and BGP Explained Jul 5, 2018 Network Address Translation (NAT) was originally described in RFC 1631. Although initially presented as a short term solution for preventing the IPv4 addresses depletion, it is still being used.

NAT (Network Address Translation) is used for security by reusing IP-addresses. The router on which Network Address Translation is configure translates traffic which is accessing internet or coming back to local network. A NAT is the virtualization IP-addresses. 2020-11-17 2020-03-21 Humphrey CheungSouthern California RouterGods Meetup 2020-11-30 2020-11-17 Hi all, Setting up a outbound NAT rule for only two of the networks behind my firewall (I have many, but these two have private RFC1918 netblocks, and I want to NAT them outbound to a single public IP addr, that is not the outside int's address.)

2.3 Port Address Translation (PAT) or NAT Overload. PAT is a type of dynamic NAT which maps multiple private IP addresses to a single public IP. Network Address Translation (NAT) is a process in which one or more local IP address is translated into one or more Global IP address and vice versa in order to provide Internet access to the local hosts. Also, it does the translation of port numbers i.e. masks the port number of the host with another port number, in the packet that will be routed to the destination. Each NAT mapping uses approximately 160 bytes of memory.
