Per Microsoft, these are the ports that Active sync uses (http://support.microsoft.com/kb/259369)
ActiveSync 4.x requires the following Winsock Transmission Control Protocols (TCP) to be available:•990 (RAPI) •999 (Status) •5721 (DTPT) •5678 (Legacy Replication) •5679 (Handshake & Legacy Replication) •26675 (Airsync) If socket port filtering occurs on any of these Winsock ports, ActiveSync does not synchronize with Microsoft Windows mobile devices.
You will need to monitor all the ports.
