Chapter 3. Data Grid Ports and Protocols

As Data Grid distributes data across your network and can establish connections for external client requests, you should be aware of the ports and protocols that Data Grid uses to handle network traffic.

If run Data Grid as a remote server then you might need to allow remote clients through your firewall. Likewise, you should adjust ports that Data Grid nodes use for cluster communication to prevent conflicts or network issues.

firewall-cmd --add-port=11222/tcp --permanent
firewall-cmd --list-ports | grep 11222

# firewall-cmd --add-port=11222/tcp --permanent
success
# firewall-cmd --list-ports | grep 11222
11222/tcp
