METHOD FOR ALLOWING AND BLOCKING A USER PC WHICH CAN USE INTERNET AT THE SAME TIME IN A PRIVATE NETWORK THEROF A METHOD FOR ANALYZING AND DETECTING A JUDGEMENT ABOUT WHETHER NAT(NETWORK ADDRESS TRANSLATION) CAN BE USED OR NOT USING A TRAFFIC DATA, AND THE NUMBER OF TERMINALS SHARING NAT

摘要

The present invention provides a method consisting of a step for analyzing a traffic receiving mirroring, a step for judging whether NAT (Network Address Translation) use of a client configuring and using a private network as well as a provided authorized IP (an Internet IP) is allowed or not, for analyzing and detecting the number of sharing terminals, a step for creating a database using data, and a step for formulating a policy by using information in database, so that when the users of a private network connect to Internet at the same time, permission or blocking of Internet use can be executed selectively.
