I blocked some people from using the Internet on the LAN, but I needed to be able to send and receiv

Change to a slightly better router with some basic online behavior management features.

It allows a computer or a subset of computers (user groups can be set) to access only a certain computer or a group**, or that certain computers are restricted during certain periods. These restrictions and groupings are all under your control.

For example, you can set the IP range between computers from 8:00 to 12:00 every Monday to Friday, and only access the domain name **.

This way, any access request that does not comply with this rule will be denied and will not be accessible. If you are reluctant to spend money to buy a router, go to the Internet** "Yaozhi ** server" or other similar **server software, install it on a computer you want, and then ban all other computers on the router, and then go to other computers to set up Internet access through the **server, and the server address is the computer where you installed the **service software. **Server software generally has the Internet management functions mentioned above.

At least there is a remote ccproxy, and the setup is very simple, just look at the help that comes with the software.

Ref. 104It's always wrong to step on someone to death.

It should be bound by the network management IP and MAC address,If your colleague can access the Internet,You install **Internet software**Internet software on your colleague's computer,That is**Internet access,You choose**Internet access,**Server and port is the IP address of your colleague's computer and**Internet port provided,Ten years ago, I used ccproxy software,I haven't used it again.,Don't use it.,You still need it.,What don't you understand about the operation of the software, there should be a tutorial on it.。

The IP address cannot be repeated, if you use the IP of a colleague and he does not change it, you will not be able to access the Internet.

If you can't access the Internet after changing the IP, it means that your computer's MAC address has been bound to the router. You need to log in to the router to change the configuration, but the router administrator password must only be known to the NMS. So in the end, let me tell you, let's die of this heart.

Extranet is not possible.

It depends on what specific policy is used to restrict, if it is for your MAC address, you can only change the network card.

If the solution is to specify the MAC address to pass, and the other MAC addresses are blocked, don't toss, you can't get it.

The network management has the management authority of routing or core equipment, and it is not a problem to restrict individual computers from surfing the Internet.

This should be the company's internal behavior management software, it is possible that your colleague forced the shutdown of this behavior management software, not by changing the IP address to operate, or the company's centralized network management tool at the end of the network to do traffic management, or filtering, in this case it should be through the firewall or router to give a specific MAC address permission.

It should be used by the network management for Internet behavior management, using IP+MAC address binding. You can change it to an IP+MAC address that can access the Internet, and change your colleague's IP+MAC address to the last digit for later changes.

。。。I don't quite understand what you're trying to say. You're saying you're restricted from surfing the Internet by the webmaster, right? Then directly call the network management to lift... Who doesn't need to go to work now without the Internet!

Change the IP, test which segments of his restricted IP are and which segments are not restricted, and use those IPs

He is not restricting your IP address, he is restricting your MAC address.
