Creating Network Interfaces

 

Creating Network Interfaces

A network interface enables an Azure VM to communicate with the Internet, Azure, and other on-premises resources. A VM can have one or more network interfaces.

For Aruba Virtual Gateway deployment, Aruba recommends that you create a separate network interface for each traffic type and map these to subnets in the following order:

• NIC1—Management traffic
• NIC2—Internet traffic– Requires a Public IP for connectivity to Aruba Central
• NIC3—VPN traffic
• NIC4—LAN traffic

1. To create network interfaces follow these steps:
   1. In the Azure portal, click Home > +Create a Resource .
   2. On the Home page, enter network interface in the search box to access the Network Interface page.
   3. Click Create.
   4. In the Create network interface window, configure the following parameters:
   • Name—Enter a name for the interface; for example, NIC1.
   • Virtual network—Select the VNET to which you want to add the interface.
   • Subnet—Select the subnet that you want assign to the interface.
   • Private IP address assignment— Based on your configuration requirements, select either Dynamic or Static addressing.
   • Network security group—Select the network security group to which you want to attach this interface.
   • Subscription—Select the subscription.
   • Resource Group—Select the resource group to which you want to map the interface.
   • Location—Select the geographic location of your VNET.
   5. Click Create.
   6. Repeat these steps to create additional network interfaces, for NIC2, NIC3, and NIC4.

2. To enable IP forwarding for NIC2, NIC3, and NIC4, follow these steps:
   1. In the Azure portal, go to Home > Resource groups.
   2. Select the resource group associated to your VNET.
   3. From the list of network interfaces, select the NIC.
   4. Under Settings, select IP configurations.
   5. Configure the following parameters:

   IP forwarding settings

   IP forwarding— Set to Enabled.

3. To add Public IP to iNeT, follow these steps:
   1. Under Settings, select IP configurations.
   2. Set IP forwarding to Enabled.
   3. Click Save.
   4. Click the listed ipconfig1.
   5. In the new window, set the Public IP address as Enabled.
   6. Click Save.
