Forwarding Ports during Offsite Virtualization

Follow

1. Background 

Partners now have more control in determining how their virtual machines in the Datto Cloud are accessed by external computers over the internet.

This article shows how to configure the private IP address of a virtual machine in the Datto Cloud. This is supplemental material to the Knowledge Base article Configuring an Offsite VLAN.

2. Port Forwarding Options

After configuring the VLAN and booting the VMs, the Port Forwarding button is available on the main page of the Recovery Launchpad (login required).

3. Remote Connection to the VM

Navigate to the drop-down menu labelled “RDP” on the main Recovery Launchpad page. Windows users can immediately initiate a Remote Desktop Connection session to their virtualized system. Alternatively, use the credentials provided in order to authenticate your remote session using a third party RDP client.

Remember: Use the [Ctrl + Alt + End] hotkeys to unlock the login screen if you are using the built-in Windows RDP client.

4. Finding and Configuring IPv4 Addresses

Depending on how you want to configure your IP scheme, you will either want to (a) find the IP address that DHCP has automatically assigned your VM, or (b) configure your own static IP address.

(a) Finding the IP Address

  1. Run the program cmd.exe. Type ipconfig and hit the return key.
  2. Look for the adapter that has a DNS Suffix containing the name of your VLAN (that you created at the start of the Recovery Launchpad) in its sub-domain.
  3. Your DHCP address will be in the row labelled IPv4 Address.

(b) Configure a Static IP

  1. Identify the correct adapter using the steps above.
  2. Navigate to the Control Panel > Network and Internet > Network & Sharing Center > select Change Adapter Settings.
  3. Right click the adapter and select Properties.
  4. Click (not check) the Internet Protocol Version 4 row.
  5. Click the Properties button, and select Use the following IP address radio button.


Figure 4 - Configure a Static IP

  • Here, you can assign a private, static IP address to the virtual machine.
  • The assigned address must exist within the range specified at the point of VLAN creation.
  • If you have forgotten the IP address scheme of your VLAN, you can view the CIDR IP address and gateway IP address by clicking the Manage VLANs button on the main page of the Recovery Launchpad.

5. Enter the IP address, and choose which ports to forward.

You can opt to forward port(s) [80] to a virtual machine.

Once the port has been forwarded, a new note appears next to the record of the virtual machine in the Recovery Launchpad interface. The public IP address / NAT is also displayed in this note.
