I have attempted to use a system based on a SuperMicro X10SLH-N6-ST031 motherboard, but it was confirmed only after I installed pfSense 6.20 on it that it was incompatible with the “multi-gigabit” NBase-T standard that AT&T is using for it’s copper RJ45 handoff. It only wanted to connect at either 10G or 1G, and since I didn’t have anything in the 10G range, it stuck to 1G, which was no better than my existing VM of pfSense. But, that was entirely my bad for not asking the seller if it was compatible, so I’ll own this failure.
After all the hoops I had to jump thru to keep the network up and working while I performed maintenance on my server, it became clear that I really need to invest in a dedicated “bare metal” pfsense box. The timing is good too because a new upgrade in the AT&T Fiber to the Home has improved my base connection from 1GB to 5GB. So I’ll be reviewing the available tech to see what I can line-up in the next month or so.
