By default, the source workload contacts the target workload to initiate the replication data transfer. The direction is controlled at the server level by the SourceListensForConnection parameter that is set to False by default. To enable the target workload to contact the source workload in a VPN setup, reconfigure the replication port direction on the Migrate Server by setting the SourceListensForConnection parameter to True on the PlateSpin Configuration page.
To configure the direction of contact for replication traffic:
Log in as Administrator to the PlateSpin Migrate Web Interface, then open the PlateSpin Server Configuration page at:
https://Your_PlateSpin_Server/PlateSpinConfiguration/
Locate the SourceListensForConnection parameter and edit its value as True or False, depending on your migration environment.
False: (Default) The source workload contacts the target workload to initiate replication. The target listens for traffic on the replication port (default TCP/3725). The replication port must be open for inbound traffic on the target workload.
True: The target workload contacts the source workload to initiate replication. The source listens for traffic on the replication port (default TCP/3725). The replication port must be open for inbound traffic on the source workload.
Save your settings and exit the page.
