THEORY
In the field of system networking, port forwarding is an implementation of network address translation (NAT) that redirects an announcement request from one IP and port number arrangement to another while the packets are navigating a network gateway like a router or a firewall.
- It consists of using a machine controlled by the attacker as a bounce box, to gain further access to the network.
