Enterprise Vault 10 Firewall Ports/Programs Required for Indexing to Work Correctly

Per this item: https://www-secure.symantec.com/connect/forums/problems-indexing-after-upgrading, disabling the firewall on the EV indexing server allows indexing tasks to correctly run.  However, I'm not comfortable turning off the firewall on the server.  Can someone please give me the ports or programs I have to allow through the firewall (Windows Server 2008 R2 Advanced Firewall) so I can create a rule and then turn the firewall back on?

Thanks

Steve
