Run 3D slicer openIGTLink simultaneously as server and client

Hello,
I would like to run 3D slicer simultaneously as server and client because I need it as client to get the tracked position with polaris vicra of the tip of a probe and also I need it as a server to send out some parameters to Matlab where I am using pyigtl.

Is it possible to run at the same time as client and server?

Yes, you can add any number of connectors in OpenIGTLinkIF as both clients and servers.
Just make sure that they are using different ports, and that you add your outgoing nodes to the server connector.
