Figure 3.11: VM networking settings
- To add inbound and outbound security rules, you have to click on either Add inbound or Add outbound.
- Once clicked on, a new blade will pop up where you have to specify settings using the following fields:
- Service: The service specifies the destination protocol and port range for this rule. Here, you can choose a predefined service, such as RDP or SSH, or provide a custom port range.
- Port ranges: Here, you need to specify a single port, a port range, or a comma-separated list of single ports or port ranges.
- Priority: Here, you enter the desired priority value. As mentioned in the Securing Azure Virtual Networks section of Chapter 2, Delving into Azure Virtual Networks, the lower the number, the higher the priority.
- Name: Specify a name for the rule here.
- Description: Write a description for the rule that relates to it here.
