Network access over Internet - Anomaly?

Could this be a bug?
My server is at and is accessible from outside (internet) according to!/cg3bur/

I have local clients (same subnet on the LAN) that work perfectly

I have remote clients that connect only when Logmein Hamachi is active. We need that VPN for other stuff but, theoretically, if Hamachi is turned off, UrBackup should still connect to the server.

Is it possible that your code looks for an interface and grabs the inactive Hamachi instead of the LAN?
