First, the firewall to open the router

(1) in the broadband router management interface, in order to click on the security settings, firewall settings, the settings on the right side of the box is selected to open the firewall options, click the Save button to enable the router firewall function.

(2) click on the advanced security settings, and enter the advanced security settings page. Here provide a number of more specific security defense capabilities, such as defense against DoS attacks, ICMP-FLOOD attacks, TCP-SYN-FLOOD attacks, filtering and filtering, etc.. Network management to do is to enable these functions, and further enhance the router's defense capabilities.

Through the built-in firewall router, we can control the security of the remote control of the router plus double insurance.

Two, set the complexity of the management account

The remote control function of the router is enabled, other users in the public network will have the opportunity to access to the router. By setting the complexity of the management account, the router is easily cracked by the attacker, by others to use.

(1) in the local area network client machine running IE browser, in the address bar after entering http://192.168.1.1 and enter, and then enter the router administrator account and password, login broadband router management interface.

(2) in order to expand the system tools to modify the login password, access to modify the login password management page, you can modify the account.

(1) in the broadband router management interface, in turn, click on the security settings, remote Web management, access to the remote Web management interface. The network management can enable remote control function.

(2) by default, routers use 80 ports to provide remote management capabilities, but this is very insecure. Can modify the port number, the use of a non - commonly used to provide remote management functions, in the Web management port bar to modify the remote management of the use of the port number (such as 1648).

(3) in the remote Web management IP in the address bar, input for remote control of the router network computer IP address.

(4) the most sensible approach is to allow a specific IP address of the machine remote login router, the parameter is set to use the IP address (such as 202.102.201.99). Now only the machine on the remote login router, while other machines are not public.
