Custom port range |
To allow a specific service port, such as a random remote port (e.g., 4125), after applying the security group, you need to create a new security group policy. Select "Custom TCP" and specify the port range as the single port you want to allow (e.g., 4125) or a range of ports (e.g., 4125-4128) if you need to allow multiple consecutive ports. The rules for security group policies specify the protocol and port range to be affected:
- Select "Allow All" to allow all protocols and ports.
- For a single port, specify the port number (e.g., 22).
- For a range of ports, specify the start and end ports separated by a dash (e.g., 22-30).
- For multiple ports, specify individual port numbers or ranges separated by commas (e.g., 22, 23-30).
- To allow all ports, leave the field empty or specify the range as 1-65535
- Authorized IP:
An authorized IP can be a single IP address or an IP address range:
- Single IP address: For example, 192.168.10.10/32
- IP address range: For example, 192.168.52.0/24
- All IP addresses: 0.0.0.0/0
- Note: Fill in the necessary remarks as needed.
4.The control panel also allows you to set security group rules and bind or unbind security groups. Please refer to the login method for accessing the control panel
5.To set security group rules, you need to create a new security group or bind an existing one.
6.Click on the bound security group to set the rules.
