We are setting up a GPO firewall for SQL Servers in a cluster and we are having issues with our failover cluster failing because the Microsoft Failover Cluster Virtual Adapter (MFCVA) is changing its IPv6 address everytime it reboots.
We are trying to set up the firewall rule to allow all communications from server A on its IPv6 MFCVA- to -server B on its IPv6 MFCVA.
Any ideas on how to essentially get the cluster working through a firewall when the cluster is trying to communicate over IPv6?
Thanks in advance!!!
