NAT hairpinning, also known as NAT loopback or NAT reflection, [27] is a feature in many consumer routers [28] where a machine on the LAN is able to access another machine on the LAN via the external IP address of the LAN/router (with port forwarding set up on the router to direct requests to the appropriate machine on the LAN).
In 2012, the IETF defined a Shared Address Space [4] for use in ISP CGN deployments and NAT devices that can handle the same addresses occurring on both inbound and outbound interfaces. ARIN returned space to the IANA as needed for this allocation and [ 5 ] "The allocated address block is 100.64.0.0 / 10 ".
Carrier-grade NAT. Carrier-grade NAT (CGN or CGNAT), also known as large-scale NAT (LSN), is a type of network address translation (NAT) used by ISPs in IPv4 network design. With CGNAT, end sites, in particular residential networks, are configured with private network addresses that are translated to public IPv4 addresses by middlebox network address translator devices embedded in the network ...
An 'Access Point Name' (APN) is the name of a gateway [2] between a mobile network (GSM, GPRS, 3G, 4G and 5G) and another computer network, frequently the public Internet. [3] Some Important APN Terms: Below are some terms of the APN settings, explaining what each setting stands for: APN: The APN address of your (mobile network operator) MNOs.
In Windows XP, NAT traversal is enabled by default, but in Windows XP with Service Pack 2 it has been disabled by default for the case when the VPN server is also behind a NAT device, because of a rare and controversial security issue. [6] IPsec NAT-T patches are also available for Windows 2000, Windows NT and Windows 98. [citation needed]

Port forwarding via NAT router. In computer networking, port forwarding or port mapping is an application of network address translation (NAT) that redirects a communication request from one address and port number combination to another while the packets are traversing a network gateway, such as a router or firewall.
In order for these protocols to work through NAT or a firewall, either the application has to know about an address/port number combination that allows incoming packets, or the NAT has to monitor the control traffic and open up port mappings (firewall pinholes) dynamically as required. Legitimate application data can thus be passed through the ...
