It is very convenient to manage the network through the router, but it must be set up, otherwise it will be very tired to manage. Now let me tell you how to set the IP address of the router and bind it with the MAC address. I hope it will help you!
First, we should log in to the TP-LINK wr841n router normally and find the IP and MAC binding option on the home page, as shown in the figure below:
Second, in the static ARP binding settings, we should first enable it, and then add a single entry, as shown in the following figure:
Third, in the binding computer, the MAC address must be accurate, otherwise it will not play any role. This must be paid attention to. After entering the MAC address, the IP address is assigned by you.
Fourth, we also have a simple way, that is, we can import directly from the ARP mapping table without inputting, so the accuracy will be better, because the MAC in the ARP mapping table is automatically captured directly in the LAN. As long as you are in the LAN and surf the Internet through this router, it will appear. Therefore, this is the best. It is recommended to bind with this method. As shown in the figure below:
Through the above methods, IP and Mac can be bound. After binding, all Internet access control and flow control can take effect, otherwise it is useless. Therefore, this item is very important and must be bound.
I. if you want to disallow the IP addresses of the intranet 192.168.1.100-192.168.1.102 from accessing all IP addresses of the extranet; 192.168.1.103 allows unrestricted access to all IP addresses of the external network. The setting method is as follows:
1. Select the default filtering rule: all packets that do not meet the set IP address filtering rules are prohibited from passing through mercury wireless router:
2. Add a new IP address filter entry:
Allow the intranet 192.168.1.103 to access all IP addresses of the extranet completely unrestricted
Since the default rule is "prohibit packets that do not meet the IP filtering rules from passing through the router", the IP address segment of Intranet computer: 192.168.1.100-192.168.1.102 does not need to be added, and it is prohibited by default.
3. After setting and saving, the following entries can be generated to achieve the desired purpose, as shown in the figure:
II. If you want the IP address of Intranet 192.168.1.100-192.168.1.102, you can only browse the external web page at any time; 192.168.1.103 from 8 a.m. to 6 p.m., it is only allowed to send and receive mail on the 219.134.132.62 mail server of the external network, and it is not allowed to communicate with the external network in the rest of the time.
To browse the web, you need to use port 80 (HTTP protocol), send and receive e-mail using 25 (SMTP) and 110 (POP), and the domain name server port number 53 (DNS)
The setting method is as follows:
1. The default filtering rule is: all packets that do not meet the set IP address filtering rules are prohibited from passing through mercury wireless router:
2. The expected purpose can be achieved after setting and generating the following items:
The above is the setting method of mercury wireless router IP address filtering.
