The port Mapping method enables access to specific port services from the Internet to the local area network internal machines. For example, the machine you are using is in a LAN connected to the Internet, all the services you open on the machine (such as FTP), by default, the outside world can not access. This is because your IP is the LAN internal IP, and the outside can access only the server you are connected to the IP, because the entire LAN on t
boot process and enter Rommon mode!
The input command changes the configuration register value to 0x2142, which causes the router to not read the configuration file in NVRAM when it is turned on. Then restart the router!The command is as follows:Rommon 1 > Confreg 0x2142//Change the configuration register value to 0x2142Rommon 3 > Re
