ABSTRACT:
The present invention relates to a method for providing internal server with reduced IP addresses, comprising: first, configure the corresponding relationship information between external address as well as other characteristic information and internal address as well as other characteristic information in the internal server; then, match the relevant information carried by the input messages received by the internal network and the output messages from the internal network with the configured corresponding relationship information respectively; finally, process the message according to the matching result. According to the present invention, WEB server and FTP server in the LAN can be easily provided without occupying too much valid IP addresses, thus, the present invention saves limited public IP addresses resource. Furthermore, the present invention implements port-level support to the internal server, and guarantees the security of network equipments.
