4.4. Managing Private Virtual Networks

To add a new virtual private network, do the following:

  1. On the Networks screen, click Create virtual network.

  2. In the Network configuration section, configure the network parameters:

    1. Enable or disable IP address management.

      With IP address management enabled, Acronis Cyber Infrastructure will handle virtual machine IP addresses and provide the following features:

      • Allocation pools. You can specify ranges of IP addresses that will be automatically assigned to VMs.
      • Built-in DHCP server. Assigns IP addresses to virtual machines. With the DHCP server enabled, VM network interfaces will automatically be assigned IP addresses: either from allocation pools or, if there are no pools, from network’s entire IP range. With the DHCP server disabled, VM network interfaces will still get IP addresses, but you will have to manually assign them inside VMs.
      • Custom DNS servers. You can specify DNS servers that will be used by VMs. These servers will be delivered to virtual machines via the built-in DHCP server.

      With IP address management disabled:

      • VMs connected to a network will be able to obtain IP addresses from DHCP servers in that network.
      • Spoofing protection will be disabled for all VM network ports. Each VM network interface will accept all traffic, even frames addressed to other network interfaces.

      In any case, you will be able to manually assign static IP addresses from inside VMs.

    2. Choose network type.

    3. Specify a name. If IP address management is enabled, specify network’s IPv4 address range in Subnet CIDR. Optionally specify a gateway. If you leave the Gateway field blank, the gateway will be omitted from network settings.

    Click Next.

  3. If you enabled IP address management on the previous step, you will move on to the DHCP and DNS section. In it, enable or disable the built-in DHCP server and specify one or more allocation pools and DNS servers. Click Next.

  4. In the Summary section, review the configuration and click Create virtual network.

To view and edit parameters of a virtual network, click it on the Networks screen. On the virtual network panel, you can change the virtual network name, gateway, DHCP settings, allocation pools, and DNS servers. To do this, click the pencil icon, enter a new value, and click the check mark icon to confirm.

To delete a virtual network, click the ellipsis icon next to it and Delete. To remove multiple virtual networks at once, select them and click Delete. Before deleting a virtual network, make sure no VMs are connected to it.
