When LLT and GAB services are started cluster wide, LLT drivers on all the nodes form connections with one another on GAB ports. In some setup configurations, operating system's firewall blocks LLT state-machine related packets which are required for forming connections. As a result, the cluster does not form and the gabconfig - a command does not show the membership.
