4. The default Receive Connector automatically created during the installation of the Hub
Transport role suffices to receive mail from the Edge Transport server. No further configuration
is required.
Hence, at the end of a manual configuration of the Hub Transport server, you should have the
connectors shown in Figure 9 - 13 .

The second scenario, which is the one recommended for the Hub Transport server, occurs when edge
subscription and EdgeSync are performed. In this scenario, to prepare the Hub Transport server, you
should perform the following tasks. The edge subscription process is discussed in greater detail later in
this chapter.
1. Ports: Verify that the perimeter network firewall that separates the Edge Transport server from
the Exchange organization is configured to enable communications on the following specified
ports. Because EdgeSync replicates data between Active Directory and ADAM, secure LDAP
port 50636 for TCP communication must be opened on the firewall to enable directory
synchronization from the Hub Transport to ADAM on the Edge Transport server. Recall
that synchronization is single directional, hence the port can be opened one - way from the Hub
to the perimeter network.
