Jonathan and Patrick

While I prefer qty 2 physical NICs I can proceed with my project if I had one \
physical and one USB NIC.  I am either going to run relayd or 1:1 binat in front of \
old network aware industrial equipment.

In the network lab I have two Gigabyte R270 ThunderX systems we were doing network \
performance testing for potential HPC use.

I appreciate both y'all's replies.

g.day

Hi Diana,

I can only agree to what Jonathan said.  I would say that the Pine64 is the best \
supported low-end machine we have.  The rPi is not that nice because of the \
interesting interrupt controller and the horrible usb controller.  I'm currently also \
looking at the NanoPi Neo2, which is very similar to the Pine64, but I want to use \
that tiny little box only as simple VPN gateway.  Are you looking for a machine with \
more than one Ethernet?  Or are you going to use a usb based ethernet?

Patrick
