Edge Gateways

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

When creating the first virtual data center in a location, an Edge router is created automatically.

The Edge router limit is shared across the entire organization and is 20 units. To increase the limit, submit a ticket.

Edge router sizes (NSX-V)

For your information

In clusters on the new network infrastructure (NSX-T), such as AMD HiFreq-1, you cannot select or change the Edge router size.

The following sizes are available for Edge routers in clusters on the legacy network infrastructure (NSX-V):

  • Compact;
  • Large;
  • Quad Large;
  • X-Large.

When creating the first virtual data center in a location within a cluster on the legacy network infrastructure, an Edge router of Compact size is automatically created — the smallest in performance and cost. Basic Firewall and NAT rules are configured on it. You can manage the created Edge router yourself, change its size, manage redundancy, NAT rules, and Firewall rules.

The size of an Edge router affects its performance. You can select the Edge router size when creating it or change it for an existing one. To increase Edge router stability and avoid packet loss and other issues, we recommend increasing the Edge router size to match the required workload.

Edge router IP addresses

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

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

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

Add IP address

  1. In the Control panel, in the top menu, click Products and select Cloud Powered by VMware.
  2. Go to Virtual Data Centers.
  3. Open the virtual data center page → Edge Routers tab.
  4. In the Edge router card, expand the IP addresses block.
  5. Click Add IP address.
  6. Specify the number of IP addresses to add.
  7. Click Add.

Delete an IP address

You can only delete IP addresses that were added manually. The basic IP address cannot be deleted.

  1. In the Control panel, in the top menu, click Products and select Cloud Powered by VMware.
  2. Go to Virtual Data Centers.
  3. Open the virtual data center page → Edge Routers tab.
  4. In the Edge router card, expand the IP addresses block.
  5. In the row with the IP address, click .
  6. Enter the IP address to confirm deletion.
  7. Click Delete.

Create Edge router

  1. In the Control panel, in the top menu, click Products and select Cloud Powered by VMware.
  2. Go to Virtual Data Centers.
  3. Open the virtual data center page → Edge Routers tab.
  4. Click Create Edge Router.
  5. If you are creating an Edge router in a virtual data center in a cluster on the legacy network infrastructure (NSX-V), select the Edge router size.
  6. Click Create.

Edge router redundancy

Redundancy increases the fault tolerance of the Edge router. All settings of the primary Edge router are automatically replicated to the backup router. The need to configure redundancy depends on the type of network infrastructure where the cluster is located:

  • legacy network infrastructure (NSX-V) — you can enable High Availability redundancy. In case of issues with the primary Edge router, failover to the backup router will occur within 15 seconds. All network hardware is fully redundant. A failure of any network device will not affect virtual machine availability from public and local networks;
  • new network infrastructure (NSX-T) — Active-Standby redundancy is enabled by default.

Enable High Availability redundancy

For your information

Enabling High Availability redundancy is only available in clusters on the legacy network infrastructure (NSX-V). In clusters on the new network infrastructure (NSX-T), Active-Standby redundancy is enabled by default.

  1. In the Control panel, in the top menu, click Products and select Cloud Powered by VMware.
  2. Go to Virtual Data Centers.
  3. Open the virtual data center page → Edge Routers tab.
  4. In the router's menu, click Edit settings.
  5. In the High Availability mode block, turn on the toggle.
  6. Click Save. The Edge router and its IP addresses may be unavailable for 30 seconds.

Change Edge router size

For your information

Changing the Edge router size is only available in clusters on the legacy network infrastructure (NSX-V).

  1. In the Control panel, in the top menu, click Products and select Cloud Powered by VMware.
  2. Go to Virtual Data Centers.
  3. Open the virtual data center page → Edge Routers tab.
  4. In the router's menu, click Edit settings.
  5. In the Size block, select a new size.
  6. Click Save. The Edge router and its IP addresses may be unavailable for 30 seconds.

Enable SSH access to the Edge router

  1. From the Control panel, open the Cloud Director panel: in the top menu, click Products → Cloud Powered by VMware → Cloud Director section.
  2. Open the virtual data center page.
  3. Go to Networking → Edges.
  4. Open the page of the required Edge.
  5. Click SERVICES.
  6. Open the Edge Settings tab.
  7. In the SSH Status block, turn on the Enabled toggle.
  8. Configure Firewall.

Delete Edge router

Before deleting an Edge router, delete routed IP addresses and networks on it.

  1. In the Control panel, in the top menu, click Products and select Cloud Powered by VMware.
  2. Go to Virtual Data Centers.
  3. Open the virtual data center page → Edge Routers tab.
  4. In the router's menu, click Delete Edge Router.
  5. Enter the Edge router name to confirm deletion.
  6. Click Delete.
