The authenticator is a network device that provides a data link between the client and the network and can allow or block network traffic between the two, such as an Ethernet switch or wireless access point; and the authentication server is typically a trusted server that can receive and respond to requests for network access, and can tell the ...
Port Control Protocol (PCP) is a computer networking protocol that allows hosts on IPv4 or IPv6 networks to control how the incoming IPv4 or IPv6 packets are translated and forwarded by an upstream router that performs network address translation (NAT) or packet filtering.
In contrast, a port which rejects connections or ignores all packets directed at it is called a closed port. [ 1 ] Ports are an integral part of the Internet's communication model — they are the channel through which applications on the client computer can reach the software on the server .

The node designated as DMZ host is the downstream firewall of the actual DMZ (perhaps the router itself isn't part of a home network) The node runs a powerful firewall capable of regulating internal security; The sheer number of ports is too great for the port-forwarding feature; Correct port forwarding rules could not be formulated in advance
Destination: Where the traffic is headed (IP address, range, network, or zone) Port: Network ports specific to various services (e.g., port 80 for HTTP) Protocol: The type of network protocol (e.g., TCP, UDP, ICMP) Applications: L7 inspection or grouping av services. Action: Whether to allow, deny, drop, or require further inspection for the ...
Port forwarding via NAT router. In computer networking, port forwarding or port mapping is an application of network address translation (NAT) that redirects a communication request from one address and port number combination to another while the packets are traversing a network gateway, such as a router or firewall.
