2.4 Network Access to Oracle Exadata Storage Servers

Oracle Exadata System Software includes the cellwall service, which implements an iptables firewall on each cell.

Additionally, the SSH server is configured to respond to connection requests only on the management network (NET0) and the RDMA Network Fabric.

To review the firewall rules, run the following command as the root user:

iptables --list

Note:

There is no firewall automatically configured for the database servers. You can implement an iptables firewall on each database server to meet your network security requirements.
