[Using Sync Home Pro with UPnP disabled on Router]

Hi all,

I'm thinking about disabling UPnP on my Asus RT-AX89X router for security reasons but I've noticed that when I do, Resilio Sync Home Pro basically stops working and begins using a Relay Server.  

My question is -- can Sync Home Pro be used without UPnP with some custom port forwarding options?  And if so, how could that be accomplished?

[Resilio Sync wants to Transfer entire drive even though it's already identical]

Hi,

I'm using Resilio Sync Home Pro with one other collaborator.  We both have identical drives and I've just set up connection between us.  But Resilio seems to think it has to transfer the entire contents of my 3.5 TB drive over to my collaborator even though we already both have identical drives.  Why is this happening?  And is there anything I can do to stop it?

Some details: the sharing settings are it's an ADVANCED folder.  I am the OWNER and my collaborator has READ/WRITE access.
