Makes decisions based on layer-3 addresses
WebRouters – Layer 3 A router has more “intelligence” than a switch because it can make decisions based on layer 3 addresses in packet headers (usually IPv4 or IPv6 addresses). Routers are used to determine how to route packets received on one interface to a network on another interface, to move the packets toward their final destination. WebPacket-filtering firewalls operate at the network layer (Layer 3) of the OSI model. Packet-filtering firewalls make processing decisions based on network addresses, ports, or protocols. Packet-filtering firewalls are very fast because there is not much logic going behind the decisions they make.
