Introduction

Rcs Virtual Private Cloud 2.0 (VPC 2.0) is a logical network interface that privately connects a server to other servers within the same subnet. To configure a VPC interface on a Rcs Windows server, you need to attach a VPC network, and manually set up the attached virtual interface with the correct IP information.

Rcs VPC 2.0 networks use RFC1918 permitted private addresses. Depending on your assigned private network address, you need to configure your Windows Server interface with the matching IP address and subnet mask to communicate with other servers on the VPC network.

This article explains how to configure a Rcs VPC 2.0 Network Interface on a Windows server. When configured correctly, servers within the same VPC can access the Windows server depending on the private firewall policies.

Prerequisites

• Deploy the latest Windows Server version on Rcs

  Upon deployment, enable a VPC 2.0 private network on the server

• Using RDP, access the server as an Administrator

View your Rcs VPC Interface Details

To configure your Rcs VPC Interface, verify your assigned VPC network details as described in the steps below.

• Open the Rcs Customer Portal

• Navigate to the Compute product category

• Find and click your target Windows Server to open your instance management page

• Within the instance dashboard, navigate to Settings

  

• In the IPv4 section, scroll and click Enable VPC

• When prompted, click Enable VPC to restart your Windows Server and attach the Rcs VPC interface

  

• Verify the assigned VPC network details and keep note of the Address and Netmask details on your VPC network

VPC 2.0

When using Rcs VPC 2.0, verify the assigned VPC network details on your Windows server as described below.

• Access your Rcs Windows Server Dashboard

• Navigate to Settings

• On the instance left navigation menu, click VPC 2.0

You have verified your Rcs VPC and VPC 2.0 network details. Depending on your assigned network address, configure the Rcs VPC interface on your Windows Server to connect to resources within the private VPC network.

Configure the Rcs VPC 2.0 Interface using Windows Network and Internet Settings (Recommended)

A Rcs VPC 2.0 network is attached to your Windows server as an extra interface that follows your main public interface naming scheme. For example, if your public interface is Ethernet 2, any additional interface starts from Ethernet 3 and increments if you attach additional interfaces. Configure your Rcs VPC Windows interface as described in the steps below.

• Access your Windows server

• Within your Windows desktop interface, find and right-click the Networks icon in the bottom right corner of your main taskbar

  

• Select Open Network and Internet Settings from the list of options

• In the open Network Settings window, click Ethernet within the Network & Internet section

  

• Verify the list of Ethernet connections, and click Unidentified Network No Internet

• On the network interface page, find the IP Settings section

  

• Click Edit to change the network interface settings

• In the pop up dialog, click the Automatic (DHCP) drop down and select Manual from the list

  

• Toggle the IPV4 button to ON

• Enter your Rcs VPC Address in the IP address field

• Enter the Rcs VPC Netmask in the Subnet mask field

• Keep the Default Gateway field empty

  

• Enter the Rcs DNS address 108.61.10.10 in the Preferred DNS field

• Click Save to apply changes to your Windows VPC interface

• Verify that your Network Interface IP Settings change to Manual with your IP details.

  

• To test that your Rcs VPC Windows Interface is working correctly, ping or access resources from any other server attached to the VPC network

Configure the VPC 2.0 Interface using Network and Sharing Center

Windows Network and Sharing Center is a control panel tool that allows you to manually set interface details on your server. Unlike the Network Settings assignment option, you can select your target Rcs VPC interface by name instead of randomly selecting the target interface. Manually configure your Rcs VPC interface as described in the steps below.

• Open your Windows Start Menu and expand the Windows System group

  

• Select Control Panel from the list of applications

• In the open Control Panel window, find and click Network and Internet

  

• Click Network and Sharing Center to open your network connections page

• Find your target Rcs VPC Interface named Unidentified Network

  

• Click the Network Interface. For example Ethernet 4.

• In the open Ethernet status popup window, click Properties

• Within the Interface properties pop-up window, select Internet Protocol Version 4 (TCP/IP IPv4)

  

• When selected, click the Properties button to open the configuration options

• In the Internet Protocol Version 4 properties dialog, select Use the following IP Address to activate the address fields

• Enter your Rcs VPC IP address in the IP Address field

• Enter your VPC Netmask in the Subnet mask field

• Keep the Default Gateway field empty

• Scroll to the DNS section and verify that the Use the following server addresses field is activated

• Enter the Rcs DNS Address 108.61.10.10 in the Preferred DNS server field

  

• Keep the Alternate DNS server field empty

• Click OK to save and apply your new Windows Interface settings

• Click OK, then Close in the Properties and Status dialog windows respectively to exit the Interface configuration mode

You have configured your Rcs VPC interface on your Windows Server. To verify that you configured the correct interface, test access to other servers on the VPC network to ensure connectivity with your Windows server.

Test your Rcs VPC 2.0 Interface Connectivity

To test your Rcs VPC Interface connectivity and verify the network details, take note of the VPC address of any other server on the network. Then, use the ping utility tool to send test network packets to the server VPC address as described in the steps below.

Replace the example Rcs VPC network address 10.49.96.4 with an actual VPC address of another server attached to the same VPC network.

• Open the Windows Start menu

• Expand the Windows System group, and select Command Prompt from the list

• In the new Command Prompt window, enter ping followed by your Windows Server VPC address you configured earlier

    > ping 10.49.96.3

  Output:

    Pinging 10.49.96.3 with 32 bytes of data:
    Reply from 10.49.96.3: bytes=32 time<1ms TTL=128
    Reply from 10.49.96.3: bytes=32 time<1ms TTL=128
    Reply from 10.49.96.3: bytes=32 time<1ms TTL=128
