Create logical networks to provide network access to workload VMs.

About this task

Your SDDC starts with a single default logical network, sddc-cgw-network-1. You can use the HTML5 vSphere Client to create additional logical networks.


  1. Log in to the vSphere Client for your SDDC.

    You cannot create logical networks using the vSphere Web Client.

  2. Select Menu > Global Inventory Lists.
  3. Select Logical Networks.
  4. Click Add.
  5. In the Name text field, enter a name for the logical network.
  6. In the CIDR Block text field, enter a CIDR block in format.

    Prefix length should be between 22 and 30, because your logical network must have no more than 1000 ports.

  7. (Optional) : Select Enabled to enable DHCP.

    If you enable DHCP on a logical network and you have configured an on-premises DNS server, you must edit your compute gateway VPN to enable DNS queries to be correctly forwarded over the VPN. Select cgw-dns-network as one of the local networks for the VPN.

  8. (Optional) : If you enabled DHCP, enter the domain name to use with VMs attached to this logical network in the DNS Domain Name text box.
  9. Click OK.

What to do next

After you have created the logical network, you can attach VMs to it. See Attach a VM to or Detach a VM from a Logical Network.

Optionally, you can use this logical network as part of a VPN connection to your on-premises data center or to an Amazon VPC. See
