### ⭐⭐⭐⭐⭐ Works with proxmox

### ⭐ Bad compatibility with Linux all around.
*by A***Y on 13 September 2026*

Arch, Debian, Fedora, Alpine... every one hangs trying to load the kernel. May be something with Supermicro hardware, but after a few hours toying around, I'm done and just returning this.

### ⭐⭐⭐⭐⭐ Works perfectly with OPNsense
*by F***O on 22 March 2024*

Upgraded my Internet Service Plan to 2 Gbps and this little gem fit the bill for my OPNsense firewall upgrade. Worked out of the box no problem. Note, however. If you encounter issues, OPNsense has a Realtek plugin with drivers you can install from the GUI
