The invention discloses a system and method achieving Telnet by traversing a network address translation (NAT) device. The system and method achieving Telnet web management by traversing the NAT device comprises steps as below. Step A, address information is acquired by an NAT technology network-listening device. Step B, a Telnet communication channel from the network equipment to a web management system is built by utilizing relay technology and the NAT technology. Step C, addressing and transmitting of information between a Telnet terminal and the web equipment is achieved by the relay technology. The system and method achieving Telnet web management by the NAT device can simplify operations of web management maintenance staff for installing and deploying web equipment, and the engineering staff do not need to be familiar with layout of kinds of NAT devices. At the same time network resources are saved, the web equipment starts to be connected with the web management when web management staff need to maintain the web equipment, and the maintenance is performed by logging in the Telnet terminal, and connection is not disconnected until operations are finished.
Description
technical field [0001] The present invention relates to the field of network technology, in particular to a system and method for a network management system to realize function traversal of a Telnet client based on NAT technology. Background technique [0002] NAT (Network Address Translation, Network Address Translation) is the process of converting the IP address in the IP (Internet Protocol, Internet Protocol) packet header to another IP address. In practical applications, NAT is mainly used to enable private networks to access public networks. This approach of using a small number of public IP addresses to represent a large number of private IP addresses will help slow the depletion of available IP address space. [0003] NAT is a wide area network access technology. It is a conversion technology that converts private (reserved) addresses into legal IP addresses. It is widely used in various types of Internet access methods and various types of networks. The reason is...
