Router / Dedicated Firewall




A router is connected to two or more data lines from different networks. When a data packet comes in on one of the lines, the router reads the network address information in the packet to determine the ultimate destination. Then, using information in its routing table or routing policy, it directs the packet to the next network on its journey.


After this nice Definition its best to say a Router is not a Firewall. A Router might have a Firewall installed in it, to allow for extra protection.
