Effective Time This rule controls the effective time period. The start time cannot be later than the end time.
The IP address range of the computer to be controlled in the local area network. For example,192.168.1.2 ~ 2 means that only computers with IP address192.168.1.2 are controlled to surf the Internet.
Port range The service port for a computer to access the Internet in a local area network. For example, 23~23(telnet port) is to control computers in the local area network to access the Internet through telnet.
This protocol controls Internet access through the protocol type used to transmit data packets.
The operation can select the status of the rule here.
Example: If you want a computer with an IP address of192.168.1.20 ~192.1.25 in the local area network, you are prohibited from surfing the Internet from 08: 00 to 20: 00 every day from Monday to Friday. The configuration is as follows:
1. Start and end time selection: 08:00 ~ 20:00.
2. Week selection: check Monday to Friday.
3. Fill in the IP address: 20~25.
4. Port range: 0~65535
5. Protocol Selection: All
6. Operation Selection: Forbidden
Example: You don't want the computer of192.168.1.3 to send files to the Internet by mail, but you are allowed to receive mail. Because the SMTP protocol for sending mail uses TCP port 25, and the POP protocol for receiving mail uses TCP port 1 10, you can achieve your goal by prohibiting the computer of192.168.1.3 from accessing TCP port 25. The configuration is as follows:
1. Start and end time selection: 00:00 ~ 24:00.
2. Week selection: check Monday to Sunday.
3. Fill in the IP address: 3~3
4. Port range: 25~25
5. Protocol selection: TCP
6. Operation Selection: Forbidden
