Firewall

The NAT router allows receiving of number of a data streams. If it receives a transmission in the form of acknowledgement or data streams or error responses from an external server due to a particular request from an internal user, then it will receive the data, translate the address to local IP address and forward it to the requesting user. By preventing all incoming requests or connections except those expected or permitted, the router acts as a "firewall".
