Transfers to the Data Store require firewalls to allow TCP port 1247 and TCP and UDP ports 20000-20399 to be open.
|Data Store Connection Port Settings|
Most users should not need to configure their firewalls, but some institutions may have more restrictive policies for security reasons. CyVerse staff will be happy to discuss any technical requirements with your networking administrators. For more information, contact CyVerse Support at firstname.lastname@example.org.
If you notice that long running transfers are terminated abruptly, be aware that some institutional firewalls have policies governing the duration allowed for idle connections that may interfere with data transfers.
For an overview on firewalls, see Firewall on the Webopedia website.
