Which type of firewall makes use of a proxy server to connect to remote servers on behalf of clients?

  • stateful firewall
  • stateless firewall
  • packet filtering firewall
  • application gateway firewall

Explanation: An application gateway firewall, also called a proxy firewall, filters information at Layers 3, 4, 5, and 7 of the OSI model. It uses a proxy server to connect to remote servers on behalf of clients. Remote servers will see only a connection from the proxy server, not from the individual clients.
