The port forwarding function would be named differently on different router or router software, The majority are called NAT or Port-forwarding. Some are called Port Forward” , RDR, Virtual Server,etc.. But the basic principle is the same one that the TCP connection or UDP connection of the certain port connected to the outside address of the router is transferred to some port of some IP address in LAN. Such corresponding relation is generally described in the form of Rules. There are generally two ways in describing this kind of “Rules”, one of which is: protocol + external port + local address + local port. The agreements are TCP, UDP or all available. When some port connection of some protocols connecting to the outside address will be transferred to some port of local address, extern port can be inconsistent with internal port. The other way is: protocol + external port range + internal address. The agreements are generally TCP, UDP or all available. When any port connected to exter
