Planning for Edge Transport Servers http://technet.microsoft.com/en-us/library/aa996562.aspx -==-==-==-==-==-==-==-==-==-==-==-==-==-==-==-==-==-==-==- Communication port settings for Edge Transport servers Network interfaceOpen portProtocolNote Inbound from and outbound to the Internet 25/TCP SMTP This port must be open for mail flow to and from the Internet. Inbound from and outbound to the internal network 25/TCP SMTP This port must be open for mail flow to and from the Exchange organization. Local only 50389/TCP LDAP This port is used to make a local connection to ADAM. Inbound from the internal network 50636/TCP Secure LDAP This port must be open for EdgeSync synchronization. Inbound from the internal network 3389/TCP RDP Opening this port is optional. It provides more flexibility in managing the Edge Transport servers from inside the internal network by letting you use a remote desktop connection to manage the Edge Transport server. -==-==-==-==-==-==-==-==-==-==-==-==-==-==-==-==-==-==-==- Besides you can also run SCW on Exchange 2007 Edge Transport Server to secure it from Windows...
