Stage 2: Disable vPower NFS IP Authorization
Starting with Veeam Backup & Replication 9.5 U4, access to the NFS Share is restricted so that it is only accessible by the ESXi host during restore operations.
When testing the manual mounting of the vPower NFS Datastore, the IP Authorization system must be disabled to allow the inbound connection from the ESXi host to the Mount Server. To disable the IP Authorization system, create the following registry value on the Mount Server associated with the repository where the backup files are stored.
Key Location: HKLM\SOFTWARE\WOW6432Node\Veeam\Veeam NFS\
Value Name: vPowerNFSDisableIPAuth
Value Type: DWORD (32-Bit) Value
Value Data: 1
After creating the above registry value, restart the Veeam vPower NFS Service.
This value disables built-in IP authentication for the vPower NFS Share and is only recommended for testing purposes. Remember to delete the value or set it to 0 after you are done testing.
