Network and firewall requirements
In addition to the ports that are used by the Veritas Access software, the appliance also provides for both in-band and out-of-band management. The out-of-band management is through a separate network connection, the Remote Management Module (RMM), and the Intelligent Platform Management Interface (IPMI). Open these ports through the firewall as appropriate to allow access to the management services from a remote laptop or KVM (keyboard, video monitor, mouse).
Table: Inbound ports lists the ports open for inbound communication to the appliance.

NetBackup uses TCP/IP connections to communicate between one or more TCP/IP ports. Depending on the type of operation and configuration on the environment, different ports are required to enable the connections. NetBackup has different requirements for operations such as backup, restore, and administration.
Table: Default NetBackup TCP and UDP ports shows some of the most-common TCP and UDP ports that NetBackup uses to transfer information. For more information, see the Veritas NetBackup Security and Encryption Guide.

For the CIFS service to work properly in an Active Directory (AD) domain environment, the following protocols and firewall ports need be allowed or opened to enable the CIFS server to communicate smoothly with Active Directory Domain Controllers and Windows/CIFS clients.
Internet Control Message Protocol (ICMP) protocol must be allowed through the firewall from the CIFS server to the domain controllers. Enable "Allow incoming echo request" is required for running the CIFS service.
