How to Configure Connections Required for Veeam Backup for Google Cloud in Highly Secured Environments

If your backup appliance is deployed in a highly secured environment with all outbound connections restricted, you must perform the following configuration steps to make Veeam Backup for Google Cloud function properly:

1. Allow internet access to the following Google Cloud APIs:
   
   • Compute Engine API
   • IAM Service Account Credentials API
   • Identity and Access Management (IAM) API
   • Cloud Resource Manager API
   • Cloud Billing API
   • Pub/Sub API
   • Cloud Storage API
   • Cloud Key Management Service API
   • Cloud Logging API
   
   To learn how to configure Private Google Access, see this Google Cloud KB article.
    
2. Allow access to the Google Cloud metadata server that stores backup appliance metadata, to the NTP server that provides accurate timing to the backup appliance, and to the Cloud DNS server. To do that, create firewall rules to connect to the address 169.254.169.254 (metadata.google.internal) through the ports TCP 80 and UDP 53, 123
   
3. Allow access to Ubuntu repositories that provide updates for the backup appliance. Ubuntu repositories are almost entirely defined by FQDNs that do not have static addresses behind them. That is why you can create the following firewall rules to receive the updates:
   
   

   Destination Endpoint	Protocol	Port
   security.ubuntu.com	TCP	80

   
   
4. Allow access to the Microsoft update server that provides updates for Microsoft .NET Framework installed on the backup appliance. Update servers are almost entirely defined by FQDNs that do not have static addresses behind them. That is why you can create the following firewall rules to receive the updates:
   
   

   Destination Endpoint	Protocol	Port
   packages.microsoft.com	TCP	443

   
   
5. Allow access to the SMTP server that sends email notifications for Veeam Backup for Google Cloud. SMTP servers are almost entirely defined by FQDNs that do not have static addresses behind them. That is why you can create the following firewall rules to send the notifications:
   
   

   Destination Endpoint	Protocol	Port
   <FQDN of your SMTP server>	TCP	587

   
   
6. Allow access to the Veeam Update Notification Server that provides security updates for Veeam Backup for Google Cloud. The server is almost entirely defined by the FQDN that does not have static addresses behind it. That is why you can create the following firewall rules to receive the updates:
   
   

   Destination Endpoint	Protocol	Port
   repository.veeam.com	TCP	443
