Urgent: access to the internet on the social security private network.

Are you from the Social Security Center? Then it is estimated that it is connected to the computer room of the social security center through a special line. Different from the concept of Internet, it doesn't go through our public network. This estimate is very difficult. If you are an ordinary unit user, it is estimated that the network management blocked you. For example, if you surf the Internet through ISA agent, you can block all websites and only let you visit the social security network. It depends on your relationship with the network administrator. Ha ha.
