It's a complete experiment with cheap network gear from China. I have a HP T730 mini PC that serves as my router. I'm installing a cheap 2.5 Gbps NIC for LAN side. Then there's a switch with 4x2.5 Gbps Ethernet and 2xSFP+ ports. My two main machines (PC and home server) are getting 10 Gbps SFP+ cards that I'll attach with DAC cables.
OS is OpenWRT, because I've been connecting over WiFi to the Internet in both old and new locations. OPNsense just will not work with any wireless adapter I've tried. I will try agan once I route Ethernet to my room.
I'm curious if all of this works with cheap network gear. Today I'm configuring a fresh OpenWRT installation on the router.
Now it gets funnier. The new 2.5 Gbps NIC just randomly appears on boot or not. I've spent half of the day to troubleshoot this and can't figure out why.
