I've tried a few different combos of settings with Win 10. I connected it between a Sharp MFP (printer) and a network switch. I sent a few pings to the printer, print jobs to the printer and SMTP send from the printer and I'm not seeing any of the traffic. I'll fire up a Linux distro and see if I can get it to work when muted. Thanks again for the help I really appreciate it! I'll let you know what I find.
