Edge routers

An Edge Gateway (EG) is a software router through which virtual machines access the network. An Edge router implements DHCP, NAT, Load Balancing, Firewall, Dynamic Routing, VPN, and other features.

When you create a virtual data center, you automatically create a Compact-size Edge router, which is the smallest in terms of performance and cost. It is configured with basic Firewall and NAT rules. You can manage the created Edge router yourself, change its size and rules.

The limit on Edge routers is shared across the organization and is 20 units. To increase the limit, create a ticket.

Edge router size⁠

The size of the Edge router affects its performance. To improve the stability of the Edge router, avoid packet loss and other problems, we recommend that you increase the size of the Edge router to fit your load.

The size of the Edge routers created can be resized.

Edge router IP addresses⁠

IP addresses are assigned to the Edge router and are used to access the virtual data center from external networks, such as the Internet.

An Edge router is always created with a base IP address.

The IP address limit is shared by the entire organization and is 20 addresses. To increase the limit, create a ticket.

Add IP address⁠

  1. In the Control panel, on the top menu, click Products and select VMware-based Cloud.
  2. Go to the Virtual Data Centers section.
  3. Open the Virtual Data Center page → Edge routers tab.
  4. In the Edge router card, expand the IP address block.
  5. Click Add IP Address.
  6. Specify the number of IP addresses to add.
  7. Click Add.

Delete IP address⁠

Only IP addresses that you have added manually can be deleted. The base IP address cannot be deleted.

  1. In the Control panel, on the top menu, click Products and select VMware-based Cloud.
  2. Go to the Virtual Data Centers section.
  3. Open the Virtual Data Center page → Edge routers tab.
  4. In the Edge router card, expand the IP address block.
  5. In the IP address row, click .
  6. Enter the IP address to confirm the deletion.
  7. Click Delete.

Edge router redundancy⁠

For your information

If you enable redundancy, the cost of the Edge router will double.

To increase the fault tolerance of the Edge router, you can enable Edge router redundancy (High Availability). In case of problems with the primary Edge router, it will switch to the backup router within 15 seconds. All settings of the primary Edge are automatically replicated to the backup Edge.

All network hardware is fully redundant. The failure of any network device will not affect the availability of virtual machines from public and local networks.

Create an Edge router⁠

  1. In the Control panel, on the top menu, click Products and select VMware-based Cloud.
  2. Go to the Virtual Data Centers section.
  3. Open the Virtual Data Center page → Edge routers tab.
  4. Click Create Edge router.
  5. Select the size of the Edge router.
  6. Click Create.

Change Edge router settings⁠

You can resize the Edge router and connect redundancy (High Availability).

  1. In the Control panel, on the top menu, click Products and select VMware-based Cloud.
  2. Go to the Virtual Data Centers section.
  3. Open the Virtual Data Center page → Edge routers tab.
  4. On the router ' menu, click Change Settings.
  5. Make the changes.
  6. Click Save. After resizing, the Edge router and the IP addresses on it may not be available for 30 seconds.

Enable SSH access to the Edge router⁠

  1. From the Control Panel, open the Cloud Director panel: from the top menu, click Products → VMware-based Cloud → Cloud Director.
  2. Open the virtual data center page.
  3. Go to Networking → Edges.
  4. Open the page of the desired Edge.
  5. Press SERVICES.
  6. Open the Edge Settings tab.
  7. In the SSH Status block, enable the Enabled toggle switch.
  8. Configure Firewall.

Remove the Edge router⁠

Before uninstalling the Edge router, delete routable IP addresses and networks on it.

  1. In the Control panel, on the top menu, click Products and select VMware-based Cloud.
  2. Go to the Virtual Data Centers section.
  3. Open the Virtual Data Center page → Edge routers tab.
  4. From the router ' menu, click Remove Edge router.
