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.
The physical gateway address is called the media access control(MAC) address or burned in address (BIA). The physical address is assigned when the device is manufactured, and cannot be changed. When a frame is sent to a device not on the local network, the gateway's MAC address is used in the frame header. The gateway address must be configured ...

IVI Translation refers to a stateless IPv4/IPv6 translation technique. [1] It allows hosts in different address families ( IPv4 and IPv6) communicate with each other and keeps the end-to-end address transparency. [2] Stateless NAT64 can be used in 4 different scenarios: [3] Stateless NAT64 is a replacement of SIIT (RFC 6145).
Oil and gas companies will have to pay more to drill on federal lands and satisfy stronger requirements to clean up old or abandoned wells under a final rule issued Friday by the Biden administration.
Crypto API (Linux) Crypto API is a cryptography framework in the Linux kernel, for various parts of the kernel that deal with cryptography, such as IPsec and dm-crypt. It was introduced in kernel version 2.5.45 [1] and has since expanded to include essentially all popular block ciphers and hash functions .
