Great Wall broadband Internet sharing

Great Wall broadband may have been bound to a MAC address of an online host or blocked from a switch. Several machines may not be able to share the Internet. I searched the online materials again, I sorted out the differences in the regions of the Great Wall broadband Internet sharing method, and the method may be different ).

1. Set route sharing for Internet access

1. vro settings

(1) how to obtain the IP address of a wide area network: The methods and names for Automatically Obtaining the IP address vro are also different. Understand the meaning and refer to the vro instructions)

2) MAC address: the length and width should not be bound to the MAC of the NIC, so you can ignore the MAC. If you must set a MAC address, use ipconfig/all on the command line to check the MAC address of the original Internet machine and set the MAC address to "wan mac address, in this way, you can pass the MAC verification.

3) IP address acquisition method and DHCP in the LAN: Generally, "automatic IP Address Configuration" is feasible. However, if there are many machines in the LAN, IP addresses may conflict. Therefore, set it to "manually allocate IP addresses", but in this way, the corresponding IP address, DNS, and gateway should be set on each machine in the LAN, it may be a little troublesome, and there will be 2 or 3 machines in the house, and it will not be very troublesome ).

4) Port ing: Generally, when routing is set, all ports of the machines in each LAN are 0 ~ 65535) ing, which is also the most convenient. However, the price of a home router is not high, and the port ing function is not powerful enough. The solution is to set the original "0 ~" in the routing port ing ~ 65535 "field ing as needed. For example, if you want to use the FTP service, it is divided into" 0 ~ 20 "," 21 ~ 21 and 22 ~ In this way, port 21 is mapped separately.

5) DHCP: It is said that the long width will detect the private DHCP service, so disable this function in the settings. Besides, it has already been set to "manually assign IP addresses" and no DHCP is required.

2. Client settings

1) IP settings: the IP address must be in the same IP segment as your route. For example, if the IP address of the route is 192.168.0.1, the IP address of your client is set to 192.168.0.2 ~ 192.168.0.255

NOTE: For the CIDR blocks that can be set by the Client IP address, see the vro instructions.

2) Gateway: Generally, routes are used for the IP addresses inside the lan. The router specification will provide a detailed introduction.

3) DNS: If the IP address is manually assigned, DNS must be set on the client. The DNS address can also be obtained using the ipconfig command.

3. login authentication

Through the above settings, all clients in the LAN can perform Network Authentication normally, and as long as one client passes authentication, other clients can access the Internet normally.

Use the long-width Automatic Login device to automatically start and log on to the Internet.

If a logon failure occurs when each machine is started, either a network fault or a client has been authenticated and can be accessed directly.

Note: The Automatic Login device will only record the account and password you have logged on to after normal authentication. If the login fails, the account and password will not be recorded. Therefore, after each machine is installed with the login device, at least one successful login is required.

2. Proxy Software + dual Nic

That is, if you use a host as a gateway, you can access the Internet normally.

1. download a CCProxy. This is a proxy server software. configure a dual-nic for the host and buy another vswitch ). 5 or 8 ports, the price is between 60-80 yuan, then the host is set (TCP/IP) protocol, set the local ip address to 192.168.0.1 mask to 225.225.225.0 gateway to 192.168.1.1

2. set client (1) the IP address is 192.168.0.2 and the mask is 225.225.225.0. The Gateway is 192.168.0.1. In the TNTERNET option, click the connection point LAN. Set the LAN proxy server address to 492.160.1. After the port is 808, enter 192.168.0.1 in the bottom line. remove all protocols from the proxy server for 808 to access the Internet. If there are many machines, change the IP address to 192.168.0.45.6.7.8.9.10 according to the client settings) and all other machines can access the Internet.

3. Others

The above two points are basically the same. Different methods are set differently.

For example, clone the mac address of the VM instance to the route, and use the route as a host for Internet sharing.
