The Network Interface Cards (NICs) include some configuration that you might be interested in. They are as follows:
- To navigate to the desired NIC, you can search for the network interfaces blade, as shown in the following screenshot:
Figure 3.16: Searching for network interfaces blade
- Then, the blade will pop up, from which you can select the desired NIC, as shown in the following screenshot:
Figure 3.17: Select the desired NIC
- You can also navigate back to the VM via | Networking | and then click on the desired NIC, as shown in the following screenshot:
Figure 3.18: The VM NIC
- To configure the NIC, you need to follow the given steps:
- Once the NIC blade is opened, navigate to IP configurations, as shown in the following screenshot:
Figure 3.19: NIC blade overview
-
- To enable IP forwarding, click on Enabled and then click Save. Enabling this feature will cause the NIC to receive traffic that is not destined to its own IP address. Traffic will be sent with a different source IP. This topic will be covered in further detail in the User-defined routing section in Chapter 4, Network Connectivity Scenarios in Azure.
- To add another IP to the NIC, click on Add, and a new blade will pop up, for which you have to specify the following:
- Name: The name of the IP.
- Type: This field will be grayed out because a primary IP already exists. Therefore, this one will be secondary.
- Allocation: Specify whether the allocation method is static or dynamic.
- IP address: Enter the static IP address that belongs to the same subnet that the NIC belongs to. If you have selected dynamic allocation, you cannot enter the IP address statically.
- Public IP address: Specify whether or not you need a public IP address for this IP configuration. If you do, you will be asked to configure the required settings.

-
- Click on Configure required settings for the public IP address and a new blade will pop up from which you can select an existing public IP address or create a new one, as shown in the following screenshot:
Figure 3.21: Create a new public IP address
-
- Click on OK and you will return to the blade, as shown in Figure 3.20, with the following warning:

- In this case, you need to plan for the addition of a new IP address to ensure that the time the VM is restarted is not during working hours.
