Ports used by Veritas System Recovery (VSR) (includes both Windows & Linux Editions)

UMI : V-370-59792-30041


Veritas System Recovery require that the following ports be opened:

  • 137 (inbound and outbound TCP and UDP)
  • 138 (inbound and outbound UDP)
  • 139 (inbound and outbound TCP)
  • DCOM:
    By default, DCOM is free to use any port between 1024 and 65535 when it dynamically selects a port for an application. This range can be reduced by creating registry keys on the computer that hosts the DCOM service; the firewall router can then be configured to forward only these TCP ports. Only a range of ports above port 5000 should be opened. Port numbers below port 5000 may already be in use by other applications and can cause conflicts with DCOM applications. At least 300 ports should be opened, because several system services rely on these RPC ports to communicate with each other. 

    Note: The VSR console must be able to reach the server by the actual IP address. DCOM cannot be used through firewalls that do address translation. For more information, consult the following Microsoft article:
  • Veritas System Recovery Management Solution (VSR-MS):
    VSR-MS is a plug-in application to the Symantec Management Platform (SMP) which is part of the Symantec IT Management Suite (ITMS).  A full list of ports used by ITMS may be found in the following Symantec article:
  • FTP:
    If offsite copy is being run to an FTP server, the ports configured for the FTP server should also be open.  By default, this is port 21 (outbound TCP) and port 20 (inbound TCP), but may vary depending on FTP server configuration
  • Cloud Storage:
    If running backups or offsite copy to OpenStorage cloud destinations (e.g. Amazon S3 or Microsoft Azure), any ports required by the cloud provider should be open.  This is typically standard HTTP/HTTPS ports 80 and 443.
