The following are the firewall configuration requirements for backups and optimized duplications. Optimized Duplication: 2049 (TCP), 111 (UDP or TCP depending on plugin version), mountd, 2051 (TCP) Backup: 2049 (TCP), 111 (UDP or TCP depending on plugin version), mountd (random) but it can be set to a static port on DataDomain system.
Requires access to TCP port 2049, UDP/TCP port 111, and the mountd port on the target DataDomain array. For optimized duplication access to TCP port 2051 is also required. If using Optimized Duplication, including Automatic Image Replication (AIR):
