After starting IPTABLES (i.e. firewall) on Node 0 of the rack, none of the RAC/CRS services on that node are working.
After trying to disable IPTABLES RAC/CRS, one node is still having problems with service startup.
After rebooting the node, the IPTABLES were still enabled and CRS still would not start.
Local connections to the instance on node 0 works, but client connections are not available.
LSNR service appears to be not working.
CRS / CLUSTER
Starting IPTABLES on one or both of the ODA nodes.
