Edge routers
An Edge Gateway (EG) is a software router through which virtual machines access the network. Edge router implements DHCP, NAT, Load Balancing, Firewall, Dynamic Routing, VPN and other features.
When you create a virtual data center, an Edge router of Compact size — the smallest in performance and cost — is automatically created. Basic Firewall and NAT rules are configured on it. You can independently manage the created Edge router, change its size and rules.
The limit on Edge routers is common to the entire 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 limit on IP addresses is common to the entire organization and is 20 addresses. To increase the limit, create a ticket.
Add IP address
- In Control Panel, go to Cloud powered by VMware → Virtual Data Centers.
- Open the virtual data center page → Edge routers tab.
- In the Edge router card, expand the IP Addresses block.
- Click Add IP Address.
- Specify the number of IP addresses to add.
- Press Add.
Delete IP address
Only IP addresses that you have added manually can be removed. The base IP address cannot be deleted.
- In Control Panel, go to Cloud powered by VMware → Virtual Data Centers.
- Open the virtual data center page → Edge routers tab.
- In the Edge router card, expand the IP Addresses block.
- On the IP address line, click .
- Enter the IP address to confirm the deletion.
- Press Delete.
Edge router redundancy
If you enable redundancy, the cost of the Edge router will double.
You can enable Edge router redundancy (High Availability) to increase the fault tolerance of the Edge router. In case of problems with the primary Edge router, a switchover to the backup router will take place within 15 seconds. All settings of the primary Edge are automatically replicated to the backup Edge.
All network equipment is fully booked. The failure of any network device will not affect the availability of virtual machines from public and local networks.
Create an Edge router
- In Control Panel, go to Cloud powered by VMware → Virtual Data Centers tab.
- Open the virtual data center page → Edge routers tab.
- Click Create Edge router.
- Select the size of the Edge router.
- Press Create.
Change Edge router settings
You can change Edge-router-size and connect redundancy (High Availability).
- In Control Panel, go to Cloud powered by VMware → Virtual Data Centers tab.
- Open the virtual data center page → Edge routers tab.
- From the router's menu, click Change Settings.
- Make the changes.
- Click Save. After resizing, the Edge router and the IP addresses on it may be unavailable for 30 seconds.
Enable SSH access to the Edge router
- From Control Panel, open the Cloud Director panel: Cloud powered by VMware → Cloud Director.
- Open the virtual data center page.
- Go to Networking → Edges.
- Open the page of the desired Edge.
- Press SERVICES.
- Open the Edge Settings tab.
- In the SSH Status block, turn on the Enabled toggle switch.
- Configure Firewall.
Remove Edge router
Before uninstalling the Edge router, delete routable IP addresses and networks on it.
- In Control Panel, go to Cloud powered by VMware → Virtual Data Centers tab.
- Open the virtual data center page → Edge routers tab.
- From the router menu, click Remove Edge router.
