Also Known As:
Application Proxy
Definition:
An application gateway is a type of firewall. All internal computers establish a connection with the proxy server. The proxy server
performs all communications with the Internet. External computers only see the IP address of the proxy server and never communicate
directly with the internal clients. The application gateway examines the packets more thoroughly than a circuit-level gateway when
making forwarding decisions. It is considered more secure, but uses more memory and processor resources.
