USB 3.0 to Dual Port Gigabit Ethernet Adapter, Rongyuxuan USB 3 Gigabit LAN Network Adapter NIC 10/100/1000 Mbps Network Adapter with Dual RJ45 LAN Ports Supports Windows and MacOS

Would highly recommend for anyone working with virtual machines and needing physical interfaces for them.This does the trick nicely with two separate interfaces. As it turns out on my home network this adapter is 10MB/s faster at transfers than the single port adapter I was using making real world transfer speeds to the NAS around 50MB/s.
