If outbound UDP datagrams are seen but no reply datagrams, then it could be a firewall blocking the port, the datagrams are not reaching RSA Authentication Manager or reply datagrams not being routed back to Unified Access Gateway. Migrating Between Clusters in Multi-DM Environment - In a multi-DM environment with two clusters assigned to different (but linked) vCenters, if you migrate a VM from one cluster to the other, the migrated VM is marked as deleted in the tenant FDB and is not available for use.
