Different Internet access permission settings for universal routing I. rule setting IP address filtering can display the default Filtering Rule and add new entries.

1. configure a rule here: restrict a computer on the internal LAN with the IP address 192.168.1.17. You can enter the URL for login only in the box below. No other operations can be performed. 2. This rule allows an intranet computer to send data packets to the Internet. The source IP address of the data packet is the IP address 192.168.1.17 of the machine to be restricted, that is, the public IP address corresponding to the added domain name. The Wan request is based on the website restrictions, so the port number is 80.

3. The rule takes effect for 24 hours. The control object is the host with the IP address 192.168.1.17. Do not enter the port next to the LAN by default. In the wan ip Address Bar, enter only the public IP addresses allowed to log on, enter 80 for the port number because it is a website. The protocol is generally set to ALL by default. Because the default rule prohibits packets that do not conform to the rules from passing through the vro, the packets that comply with the rules are allowed to pass, and the rule status is effective.

If the website is restricted in the rule and the destination request port is port 80, the packet corresponding to port 53 should be allowed, because 53 corresponds to the data packet sent to the domain name resolution server, it is used to correspond the domain name and IP address, so it must be enabled. 5. The IP address filtering rule configuration function in the general router configuration mainly analyzes the control to be performed, and then selects the default rule and configures the filtering rule.
2. the firewall sets the user's Internet access process. In fact, the computer constantly sends request packets. These request packets contain many parameters, including the source IP address, destination IP address, source port, and destination port, the router controls the Internet access permissions of different users in the internal LAN by limiting these parameters.

It is the configuration page of the general switch. If no function is used, do not select it. Apart from the general switch, there are two filtering functions. The default filtering rule is to define some specific rules on the specific rule settings page, control and process qualified data packets. The default rule specifies that the custom rule does not contain non-conforming data packets. A data packet must comply with the set rules, either it does not comply with the set rules, but it must also comply with the default rules.
