Ports 80, 443 and Ports 9350 thru 9354 need to be opened or allowed for outgoing TCP traffic in your firewall(s).

To determine or confirm that these ports are open, use Process Explorer on the computer where the RE Mobile service or RE Web service is installed.

Please contact the appropriate software vendor or IT professional for assistance with this process or issue, which is beyond Blackbaud's scope of support.
