Public VCF as-a-Service - Declaring the public IP gateway in VCD

Objective

When you order a new Public VCF as-a-Service organization, a vRack and a block of public IP addresses are delivered. To assign those public IPs to workloads, you must declare the block’s gateway inside the target VCD Virtual Datacenter.

This guide shows how to retrieve the correct gateway and add it to your VDC.

Requirements

• A Public VCF as-a-Service organization with a delivered public IP block.
• Technical administrator rights on VMware vSphere on OVHcloud.
• Access to the OVHcloud Control Panel.

Instructions

1. Log in to your OVHcloud Control Panel. Click Hosted Private Cloud, then Public VCF as-a-Service, and select your organization.

   

2. Open the Virtual Datacenters tab and select the VDC where you want to use the public IPs.

   

   In General information, verify that the vRack shown is the one linked to your public IP block.

   

3. Select the vRack tab.

   

   Locate the vRack segment named vRack segment - VLAN0 or vRack segment - PUBLIC.

   Click the three dot menu ⋮ and Add a subnet.

   

4. In the modal, enter the gateway in CIDR form for your public IP block, then confirm. The gateway is the last usable host of the block.

   Example: for 203.0.113.0/29, the last usable host is 203.0.113.6 so enter 203.0.113.6/29. You can use any standard IP calculator to verify.

   

5. Wait a few seconds and refresh the page. The subnet gateway should now appear on the segment.

   

Use the gateway when creating workloads

• When creating a vApp or VM in VCD, pick the corresponding Organization VDC network and choose a Direct network type to see the available public gateways.

Troubleshooting

• If the gateway is rejected, recheck that you entered the last usable host with the correct CIDR mask for the block.
• Ensure the VDC is attached to the same vRack that you linked to the public IP block in the previous guide Public VCF as-a-Service - Linking a public IP block with vRack.
