An application-level gateway ( ALG, also known as application layer gateway, application gateway, application proxy, or application-level proxy) is a security component that augments a firewall or NAT employed in a mobile network. [1] [2] It allows customized NAT traversal filters to be plugged into the gateway to support address and port ...
Application Layer Gateway (ALG) software or hardware may correct these problems. An ALG software module running on a NAT firewall device updates any payload data made invalid by address translation. ALGs need to understand the higher-layer protocol that they need to fix, and so each protocol with this problem requires a separate ALG.
NAT traversal. Network address translation traversal is a computer networking technique of establishing and maintaining Internet Protocol connections across gateways that implement network address translation (NAT). NAT traversal techniques are required for many network applications, such as peer-to-peer file sharing and voice over IP. [1]

NAT-PT. NAPT-PT. v. t. e. An IPv6 transition mechanism is a technology that facilitates the transitioning of the Internet from the Internet Protocol version 4 (IPv4) infrastructure in use since 1983 to the successor addressing and routing system of Internet Protocol Version 6 (IPv6). As IPv4 and IPv6 networks are not directly interoperable ...
e. dIVI Translation refers to a dual stateless IPv4/IPv6 translation technique. dIVI is an extension of 1:1 stateless IPv4/IPv6 translation ( IVI Translation) with features of IPv4 address sharing and dual translation. dIVI-PD is a further extension of dIVI to be well used in Wireline (Fiber, DSL, Cable) and Wireless (3G/4G) access environment ...
Port forwarding. 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.
It is located 9.1 NM (16.9 km; 10.5 mi) east southeast [1] of the city. The airport is named after Houari Boumediene (1932–1978), a former president of Algeria. Dar El Beïda, the area where the airport is located, was known as Maison Blanche ('White House'), and the airport is called Maison Blanche Airport in much of the literature about the ...
