To close this out, installed a second X550-T2 - The system didn't even need a network device reconfiguration since the network device driver was identical (though my Netgate ID changed - DM'd @stephenw10 to update that on Netgate's end).
Here's my final config:[image: 1740938313074-cef9bb6f-3b07-429a-8e3e-eb520a343b2e-image.png]
Everything works perfectly. With the CPU power set to ultimate efficiency, while hammering it with speed tests, I only get to 12% CPU usage. If I set the dial to midway between Perf and efficiency, I can't crack 4%. Haven't tried full perf mode yet.
Nice to know I've got power to spare in case I decide to start running more services on the box.
There are likely more efficient ways to set this up, but this works perfectly for my setup as-is. I'll likely move to using VLANs when I do some HW replacement later, but there's no rush.
