    Turns out ReadyNAS 6.4.2 for the RN202 already includes the driver (external module) for the AX88179 USB to Ethernet adapter (also sold by j5create as the JUE130), but out of the box the kernel needs to be configured for it:
     
    # cd /home/gbeddow/linux_src/linux-4.1.16-alpine

# make menuconfig

Device/Drivers -> Network Device Support -> USB Network Adapters (press "M" to enable as module)

(EXIT AND SAVE CONFIG)

Thanks for sharing your solution. Not sure why you need 3 ethernet connections to the NAS though.

    Investigating Intrusion Detection & Prevention Systems. Only 2 ethernet connections needed for Detection (typical Snort configuration), but 3 (or more) needed for Prevention.
