By default Blackbaud NetCommunity uses ports 80 (HTTP) and 443 (HTTPS).

Blackbaud NetCommunity version 6.35 and earlier also requires ports 64377 and 64378 (BBNC COM Service) be available on the NetCommunity server. These two ports do not need to be open on any hardware firewalls.

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