Supported Ports in a DR Series System
The following table lists the application and service ports found on a normally operating DR Series system. There may be
other ports that are not listed here, that an administrator may need to open and enable to support specific operations
across the network. Be aware that the ports listed in the following table may not reflect your specific network
environment, or any planned deployment. While some of these DR Series system ports may not need to be accessible
through the firewall, this information is made available when deploying the DR Series system in your own network
because it indicates supported ports that may need to be exposed.
