You need to open the following ports for each node in the firewall for communication of cluster services between
nodes:

—

TCP Ports – 30865, 5560, 7630, 21064

UDP Port – 5405

Create the file /etc/sysconfig/network/routes, and enter the following text:

default YOUR_GATEWAY_IPADDRESS - -

Edit the file /etc/resolv.conf to change the DNS IP address to the IP address of the DNS server in your
network in the following format:
