To run the virtual failover client (VFC) on a Recovery-Series appliance, you must set up a virtual network bridge and confirm or update the virtual network before setting up the VFC itself. (For more information, see Creating a virtual failover client.)
Note: This is an appliance-specific setup and not client specific. If a virtual network has already been setup for a previous VFC, you do not need to repeat this step for a new VFC.
This network bridge allows you to access the VFC in audit or live mode. When the VFC is in live mode, it uses this bridge to access the local area network of the appliance. It can then communicate with other clients on the network and access the Internet. A VFC in audit mode does not have network connectivity.
The virtual failover client (VFC) communicates with other network elements via the network bridge, which is associated with a physical Ethernet adapter (eth0, eth1, etc) on the Unitrends appliance.
Setting up the virtual network is a two-part process that involves the following:
• Setting up the network bridge
• Setting up the virtual network
Setting up the network bridge
1 Select Settings > Instant Recovery > Network Bridge. In the upper left part of the screen, you see the Ethernet adapters (and associated subnets) that the VFC uses to communicate with the other clients on the network.
2 Click to select an Ethernet adapter.
• This may be eth0, eth1, etc., or you may see only one.
• If you have more than one Ethernet adapter, use a secondary adapter for the network bridge (the one that is NOT being used for backups or replication).
3 After you click on the Ethernet adapter, perform one of the following depending on the message that displays:
• If a bridge has not been set up for this adapter, the message NO BRIDGE ATTACHED displays. Proceed to Step 4.
• If a bridge has already been set up for this adapter, a message displays in the upper right portion of the screen indicating that this adapter is attached to the bridge (such as “Network Bridge attached to Physical Adapter: eth0”). Skip to Step 8 below.
4 Click Add to add the network bridge to the adapter. You see a message confirming that you are adding the bridge.
5 Click the I understand that I am adding a bridge to... checkbox.
6 Click Confirm. In the upper right part of the screen, you see a message that the network bridge is attached to the physical adapter and the physical Ethernet adapter you selected.
Note: You also see a Remove button you can use to remove this adapter, if necessary.
7 Click Close. Continue to the steps for setting up the virtual network.
Setting up the virtual network
8 Select Settings > Instant Recovery > Virtual Network. In the upper left part of the screen, you see the default value of the virtual network. It may take a moment to load.
9 If the Virtual Network address conflicts with a subnet used in your environment, you can change this address as needed.
Note: The DHCP Range is a pool of IP addresses from which IPs are assigned to the VFCs you create. For example, with a DHCP Range of 192.168.53.2 - 192.168.53.25, the address for the virtual network can be from 192.168.53.2 to 192.168.53.25, and you can change the last number to a number between 2 and 25 (as long as the number is not being used already).
10 Click Confirm to establish the virtual network. You see a message that the network address is successfully set.
11 Click Okay.
