SMB over port 139 or 445?

Hello, I have a windows 2k12r2 server hosting a CaperShare behind a firewall. I've opened port 139 in the firewall but clients cannot connect to the server. OS X gives me a "There was a problem connecting to the server..." error. If I turn the firewall off and connect to the share manually, I see (via wireshark) clients successfully connect using SMB2 over port 445. Do I need 445 open in the firewall too? or can I force connections over 139 somehow?

Thank you!
