Description
This occurred in one case - but the symptoms and workaround are worth noting in case other clients experience the same issue.
Client had Windows 2012 servers with 2 interfaces, but noted RV is picking the wrong one to bind to. This is only occuring on Windows 2012 and not on 2008 R2. The secondary NIC was for for our backup environment and so not routable to most hosts.
Client had installed RV 8.4.5 (for the fix for RV-3501) but still noted the issue occuring.

Issue/Introduction
Client noted RV daemon continually binding to wrong inyterface when running on Windows 2012 servers. They had installed RV 8.4.5 (for the fix for RV-3501) but still noted the issue occuring.
Environment
Windows 2012 Server
Resolution
Root cause of the issue was found to be that the secondary (scheduled backup interface) was set to a higher speed than the primary one - because of this the automatic metric applied caused priority to change causing this to be automatically selected.
The Automatic Metric feature assigns a higher metric to the slower network interface detected.
Client changed this - setting the metric from "Automatic" to 1 and that allowed the correct interface to be chosen.
