Challenge
In rare cases, when you perform a failover, Re-IP rules are applying correctly, however, when you perform a lab test these rules would not be applied.
Solution
To resolve that:
1. Make sure that no plans are currently running
2. Open Veeam Availability Orchestrator UI > Configuration > VAO Agents, select affected agent and click Edit.
3. Then just walk through the settings and click Finish at the end.
