It is forbidden to pull network cables or connect to routes and switches on the switch without permi

It mainly depends on how your primary router is, that is, the main router.

You set all users to be authenticated to access the Internet.

You can assign PPPoE, or Web or direct ARP, which is what you call MAC address and IP binding to the customer to surf the Internet. So, don't worry. The router can control the MAC address of the host connected to the back of the switch, and your top priority is to need a main router that prevents small routers from being messed up, which is the point.

I recommend using a Dimension or Sea Spider router.

Hope it helps.

But can the router still control the MAC behind the switch? What a concept.

Put the mac as a filter tube, who you are, and no one who knows your password is on it.

The premise is that your routing is manageable. But the burden of management is greater.

The switch also surfs the Internet through the MAC address, and you can set your route.

That is, you can just join the Mac with Internet access and pass it.

To be honest, I don't know much about this, but I do understand some. See if you can set the back computer IP to fixed, and then turn on the IP address and MAC filtering in the security settings! Anyway, the router is only these 255 IPs, there are many computers with multiple IPs, it should be feasible, I highly recommend you try it!

You can control the IP fixedly, forget the specific settings, only the estimated enterprise router, you can control whether the IP has traffic through, but the user private route is separated, and it can't be controlled.

In this case, it is physically difficult to control the situation of private router switches, etc., it can only be a combination of software and hardware, share our solution:

1.First of all, the IP address acquisition of the entire network is set to automatically obtain, open the DHCP server, some routers have this function, or use a computer to set up a DHCP server, 2In DHCP, each company computer is recorded, and the IP address is bound to the MAC address, so that external devices connected to the company network cannot obtain the IP address. Routers included. If you want to use the corporate network, you must go to the NMS to open it.

3.If your current route and gateway address information is static, it is recommended to change to the same network segment after it is automatically obtained.

The above is a more realistic solution for your current equipment.

There is also a solution that is more convenient, but you need to replace the main routing equipment, and set the authentication mode of the company's Internet access to the web authentication mode, that is, the client needs to go online and must pass the authentication of the web page to access the Internet, so that it is useless to connect to the private router, remember that the low-end dlink has the corresponding function of the router, and the login page will be displayed when you open IE after application, and you must have a username and password (this is of course assigned by the network management).

Regarding the sharing and connection between you and the machine under different gateway routes, you need to set the operation mode of the router, which cannot be carried out in the way of routing, but should be operated in the mode of the bridge, which may be set in some routers. Different routers have different ways to set up, but it's safe to assume that if the route pattern is not shared. Because it's two subnets.

IP conflicts probably don't happen, and theoretically this connection doesn't cause conflicts.

If you want to limit it, it is estimated that there is no way.,Ordinary routers generally don't support it.,Now routers MAC can be burned.。

If you want to share the connection, you can only add a static route table to the original route so that all the information can be sent to the new route.

I've been reading it for a long time and I don't understand what you want? Don't let people use the router for private use? Then you can directly use the MAC address binding method to make their router unable to access the Internet.

If you want to prevent IP conflicts, you just need to enable DHCP, how can the gateway of other router conflict with your IP?

If you want to share and access with all machines, don't connect the WAN port from the router, just use the LAN and use the router as a switch.

Set it up in your router.

Bind your Mac to IP addresses and then only allow those addresses to pass through your router. ok。

Routers are used to connect networks, that is, to connect different networks.

Routing can automatically assign IP addresses to your LAN computer! Implementing a virtual dial-up switch can only be used to distribute network data! In layman's terms, a network cable is divided into a number of followers, so connecting the router first and then the switch can solve the problem Agree that the optical modem on the first floor can access the Internet normally?

Go to the router settings, turn off the MAC binding, or add your computer's MAC to it.

You connect the router first, and then try to connect the switch.

The route is set up to go directly to the Internet.,Your cat out of the line computer to dial the number to go online.,I don't know what you're doing there.,Is there less interface?。

Try it according to the dynamic IP setting:

Plug in the router, do not connect the home network cable first, reset the router (restore to the factory), connect the computer to any LAN port of the router, enter the settings page, and set it according to the dynamic IP mode. Then set the SSID, encryption method, and password. Save, restart.

After setting up, connect the home network cable to the WAN port of the router.

Local Connection--Right-click Properties--- Configuration--- Advanced --- MediaType 10Mbps Full Duplex (the default is Auto or Auto), try it with this method, if not, consider network cable problems, such as line sequence, network cable quality, crystal header.

If possible, first test whether the router line can access the Internet, and if it can't access the Internet, check the switch.

Connecting the WAN port can also allow the access devices under the secondary router to access the Internet, but not in switching mode and routing mode.

1. First of all, you need to change the default gateway address of the secondary router (unless the gateway of the secondary router is determined to be different from the gateway of the main router), enter the router setting interface, select the LAN port setting, and change the original IP address to other free IPs. For example, if the primary router is , and the secondary router is also by default, then change the secondary router to .

2. The original network cable connected to the LAN port (the network cable that can be connected to the LAN port of the main router) is connected to the WAN port of the secondary router.

3. Enter the router settings interface, in the Internet settings (where the broadband account and password were originally filled), select the connection mode as "static IP", and fill in the IP address, mask, gateway and DNS correctly in the gateway segment of the main router. (It is also possible to set a dynamic IP, but for network stability, it is recommended to use a static IP).

4. Other settings of the secondary router, such as turning on DHCP, turning on wireless related functions of the wireless router, etc., save and restart the router.

4. Then the LAN port will be connected to other wired Internet equipment.

Unless the IP address of the computer you are connected to at the LAN port is within the range of the router gateway.

You probably want to connect another computer, and then you find that there are not enough ports. Because the general route has 1 WAN port and 4 LAN ports, which can only be used as a switch, 1 in and 3 out, so only 3 computers can be used at the same time. Your fourth computer, there is no room to use.

There are 2 solutions:

1. Buy a switch and expand it or replace it directly (generally the switch is 8 ports, and 7 can be connected);

2. Change the router of the switch to router use, cascade, that is, the router is connected to the router, the physical connection is very simple, the LAN port line of the superior router is connected to the WAN port of the lower router, so that the 4 LAN ports of the lower router can be used. However, to enter the lower-level router to set it, the network parameters - > WAN port parameters are changed to dynamically obtain the IP address; The LAN port parameter is changed to the default of the general higher-level router or, the principle is that the network segment is different from the higher-level router, which can be used), of course, DHCP should be enabled.

The remaining WAN ports cannot be directly connected to the computer, and can be connected to a router to surf the Internet.

Oh, it's very simple to go into your router and look at the host connection status, you can display the current host list, if you find an unexpected situation, you can set the MAC to bind to the IP, so that even if he uses the switch, it is useless.

Every router has MAC address filtering, don't you set it up? That's how I take control.

The second floor is right.,Restrict MAC,Specify MAC to access the Internet,At the same time, bind the IP to the MAC,So that you must have the corresponding MAC and the corresponding IP to access the Internet。

Lighting does not mean that he is surfing the Internet, it will be on if he turns off the power and does not pull it out, and flashing is in use! It shouldn't be easy to stop him again! You.

His indicator light is on 24 hours a day... You go to the next LAN management software, and it seems that you can limit it.

Buy a managed switch, control the speed of each interface, and freeze the IP address, so that you can sit back and relax.

It is on 24 hours.

His house is a desktop computer bar, and the power supply of the desktop is generally connected for a long time, so even if the network card is turned off, it is still running! So the lights in his house are always on!

In your case, you can go out of the switch directly to the computer to automatically obtain the IP to surf the Internet, then connect to the WAN port of the router, and the router can be directly used in dynamic IP mode.

If you say this, if the router is normal, you will not be able to access the Internet if you connect directly to the switch.

Answer: If your broadband home line can access the Internet without dial-up, then you can use both devices as switches.

Needless to say, the switch can be used normally, and the WAN port of the router should not be connected to any line, just use the LAN port. To put it bluntly, the router is used as a switch.

The connection is incorrect.

It is the WAN port of the main line of the home connection, the router sets the broadband account and password, the switch is connected to the router LAN port, and the computer is connected to the switch LAN port to access the Internet.

The main line is connected to the WAN port of the router, and the switch is connected to the LAN port of the router, and DHCP is set in the route

The main line of your home has been separated from the router, if you use the router to drive it first, plug in the WAN port of the router, and set the WAN of the router to a static IP. If you don't want to do a secondary route, you should not plug in the WAN and turn off the DHCP on your own router to avoid conflict with the DHCP of your home main line.
