xDot in Packet Forwarding mode

Good Day -

We’ve been using xDots and Conduit gateways successfully for several months in a client application with gateways in Network Server mode.

We have a new application that would be better suited to Packet Forwarding mode. We see documentation for the Conduit in Packet Forwarding but nothing about the xDot.

+ does the xDot need to be configured differently for Packet Forwarding mode?
+ is security between the xDot and Packet Forwarding gateway discussed anywhere?

Thanks in advance for your help.
