What is alg.exe process in Task Manager

The process alg.exe is a valid Windows system process running in the background. The alg.exe file is a trustworthy file from Microsoft. This process stops or sends data on open ports to the network or the Internet. The process alg.exe there can also be recorded and monitored inputs. ALG is an acronym for Application Layer Gateway.

Application Layer Gateway Service is a component of the Windows operating system. And 'if you are using a third-party firewall or Internet connectionSharing (ICS) to connect to the Internet. This program should not be terminated by Windows Task Manager, or lose all access to the Internet until you restart the computer when the process starts.

The executable can alg.exe computer applications from a client machine dynamically to the passive use of TCP / UDP ports for communication with the well-known ports on the server machine to access applications residing alone machinethe presence of a firewall.

Berserker at all to solve the problem, the server initiates the connection, the client and the firewall to go for FTP connections was developed various methods. This was known PASV passive mode, or, to use education as a client saying that the server is in deficit.

In passive mode FTP the client initiates both connections to the server, solving the problem of firewalls filtering the incomingData port connection to the client from the server. When you open an FTP connection, a privileged client opens two random ports locally (N> 1023 and N +1). The first step is used for communication, that is, (it is the well-known port for FTP connections 21) contacts the server on port 21, but then instead of a PORT command and so the server returns the connection to the data port that the client is the question of PASV (passive) command. The result is that theServer opens a random unprivileged port (P> 1023) to itself and sends the PORT P command back to the client. The client initiates the connection from port to port N +1 P on the server for data transfer.

alg.exe The process uses port 1025 by default for your attention. The absence alg.exe file might block the security protocol to communication ports.

The conversion of the address information for the network layer can be treated withalg.exe process that extracts data from the payload application residing within the dictates acceptable to the host address on both sides of the NAT or firewall.

The function on the alg.exe process is similar to a proxy server that sits between the lines of communication of the client and the server computer to facilitate real data.
