Hello,

My better half is going out of town this coming weekend and taking his laptop with him.  I provide technical support, as I'm the computer person of the home.  Will Multiplicity work outside of our private home network (e.g. 10.0.0.X)?  If yes, what do I need to do to configure the secondary (his) and the primary (mine)?

Thanks!

MP is designed to work on the same subnet; not across other networks or over the Internet.

Yes, that would work.  If you have each connected to a VPN, that puts it on a shared / same subnet, that would work.

You would likely want to add the Secondary by IP instead of HostName:
