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 ...
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]
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.
Circuit-level gateway. A application level gateway is a type of firewall . Application level work at the session layer of the OSI model, or as a "shim-layer" between the application layer and the transport layer of the TCP/IP stack. They monitor TCP handshaking between packets to determine whether a requested session is legitimate.
