Use LAN access control software and LAN Access prohibited software to restrict computer access

Use LAN access control software and LAN Access prohibited software to restrict computer access
In the lan network management of a company, we sometimes consider network security. We need to prohibit LAN computers from accessing the internet to prevent various negative effects of random internet access. You can use either of the following methods to achieve this:
 
Method 1: Prohibit the computer from accessing the internet or control the computer's surfing behavior through the vro.
 
The advantage of using a vro to restrict computer access is that you can make full use of the functions of existing network devices without deploying other hardware and software devices. At the same time, most mainstream routers currently provide functions to manage computer usage and control computer internet access.
 
For example, if you want to disable computer internet access, you can simply use the "MAC address filtering" function in the vro. For example, you can set "only allow specific MAC addresses to access the Internet ", in this way, you can add the MAC addresses of computers allowed to access the Internet in the company. In addition, all other computers cannot access the Internet. Of course, if you do not add any MAC addresses, this means that no computer on the LAN can access the Internet. As shown in:

At the same time, vrouters can also be used to control computer internet access behaviors, such as prohibiting P2P downloads, stock trading, and gaming. As shown in:

Of course, after all, the main function of a router is to provide Internet services for LAN computers, so it is not recommended to set too many filters; otherwise, it is easy to increase the load of the router. At the same time, vrouters have weak functions in filtering P2P software, stock trading, chatting, and playing games. They cannot completely block complicated network applications, such as thunder downloading and QQ games. At the same time, vrouters are upgraded slowly, the failure to block various network applications in real time leads to certain limitations in the control of computer internet access. In addition, the configurations of some vrouters are complex and not suitable for general managers. In this case, you can consider using the second method.
 
Method 2: Use a dedicated LAN to control Internet Access software to restrict Internet access by computers and filter Internet access by LAN computers.
 
In view of the limitations of routers in controlling computer internet access behavior management, many organizations have deployed dedicated LAN Internet access control software and network monitoring software to achieve LAN Internet access control. At present, there are many specialized lan network management software in China, for example, there is a "jusheng network management" (: http://www.grabsun.com/soft.html) software, just need to deploy in a computer, you can scan all the computers in the LAN, you only need to assign a policy for the computer to control the Internet access. For example:

At the same time, the jusheng network management software can also control computer downloads, in particular, prohibit the upload of thunder, prohibit the PPlive Network TV, prohibit the PPS upload, prohibit the opening of video websites, prohibit stock trading, prohibit computer games, prohibit online shopping, etc, this can effectively control the computer's above unreasonable online behavior. As shown in:

In addition, through the "jusheng Network Management", you can also control the computer network speed, limit the lan network speed, and prevent the LAN from snatching the network speed, as shown in:

In short, the LAN can prohibit computers from accessing the internet or Control LAN computers. On the one hand, you can use existing LAN network devices, such as routers, switches, and firewalls. On the other hand, you can also use a dedicated network behavior management system and LAN to control the Internet access. No matter what method you use, you can achieve effective Internet access control. However, compared with vrouters, managing computer internet access through specialized network monitoring software is simpler and more direct, the specific method, enterprises and institutions can choose according to their own needs.
