A circuit-level gateway is a type of firewall. Circuit-level gateways work at the session layer of the OSI model, or as a “shim-layer” between the application layer
Because a circuit-level gateway filters packets at the session layer of the OSI model, this gateway operates two layers higher than a packet-filtering firewall does.
