Challenge

A Surebackup job fails with the error "Error: No destination network for IP address"

Selecting the individual server from the list of VMs within the status window the following is seen:

Cause

When a VM is Powered On by the SureBackup job Veeam Backup & Replication will detect its IP address. If the detected IP address does not match match the Virtual Lab's isolated vNIC subnet, the error "No destination network for IP address" will occur.

Solution

Training Video

We encourage you to watch this 15 minute video which covers how the Virtual Lab works, and how to configure it.

https://www.veeam.com/videos/virtual-lab-configuration-15466.html

If this error occured while using "Basic single-host" on the Networking tab, switch to "Advanced single-host" and manually configure the correct Isolated Networks, and appropriate  Network Settings for those Isolated Networks. For more information on configuring SureBackup with "Advanced single-host" please watch the video above, or review the following documentation:
https://helpcenter.veeam.com/docs/backup/vsphere/create_vlab.html

 


 

To resolve this issue review the Network Settings of the Isolated Networks within the Virtual Lab. The IP address in the Network Settings must match the gateway IP that the VM being powered on by the SureBackup job is expecting.

If the IP in Network Settings is correct, make sure that the Mask also matches production as this could cause the wrong subnet to be specified.

 



Example:

For the error show at the begining of this KB article, the settings which caused this to happen were as shown here:

After reviewing the network settings of the production server, the issue was identified. As shown in the screenshot below the gateway IP that the server is expecting does not match the VLab's Network Settings above. The combination of the incorrect IP address with the correct Mask has caused the Virtual Lab to be expecting the VM to have an IP in the 192.168.148.1/24 subnet. Which is exactly why when the VM presents with the IP 192.168.0.3 the error "No destination network for IP address" occurs.

The Network Settings were corrected as shown below, and the SureBackup job worked.
