Veeam Backup & Replication 9.5 Update 4

Managing Public IP Addresses

It might be required that one or several replica VMs should be accessible from the internet after full site failover. To accomplish this, all VM replicas on the cloud host that need to be accessed from the internet must have public IP address.

With Veeam Backup & Replication, the SP can allocate in his/her network infrastructure a pool of public IP addresses and provide one or several public IP addresses from this pool to the tenant. The tenant can specify public IP addressing settings at the process of the cloud failover plan configuration.

Managing Public IP Addresses Note:

Consider the following:

  • The SP does not need to allocate public IP addresses in Veeam Backup & Replication if the SP uses vCloud Director to provide replication resources to tenants. Instead, the SP configures the NSX Edge gateway in the properties of the Organization vDC that will be used as a cloud host for tenant VM replicas.
  • To enable access to a tenant VM replica by a public IP address, the SP must properly configure port forwarding to the SP network extension appliance in the production network infrastructure.
  • It is recommended that the SP plans network resource allocation and allocates public IP addresses in advance. However, the SP can also create or edit a pool of available public IP addresses when subscribing a tenant to a hardware plan. To learn more, see Specify Network Extension Settings.

When the tenant's production VM fails over to its replica on the cloud host during full site failover, Veeam Backup & Replication assigns a specified public IP address to the network extension appliance on the SP side. The network extension appliance redirects traffic from this public IP address to the IP address of a VM replica in the internal VM replica network. As a result, a VM replica on the cloud host can be accessed from the internet.

To configure a pool of public IP addresses:

  1. Open the Public IP Addresses Assignment dialog window in one of the following ways:
  • Open the Cloud Connect view, click the Cloud Connect node and click Manage Public IPs on the ribbon.
  • Open the Cloud Connect view, right-click the Cloud Connect node and select Manage public IP addresses.
  1. Click Add and select IP address range to add to the pool several public IP addresses at a time.
  2. In the Public IP Address Range window, specify the first and the last IP address in the range of IP addresses you want to add to the pool.
