Review: Solution for "Forbidden Router" - 4 ports, each 2.5 GbE. These works fine in Linux, and hence in Proxmox. I have two of these cards running behind a pfSense virtualized router, and haven't noticed any performance or heat problems. Do make sure you have ventilation for the card, but I haven't noticed this card running especially hot. 2.5 GbE is the new 1 GbE in 2025, and should be the minimum now for household networks, especially if you want to take advantage of the new higher WiFi speeds. It's a good add-on to an existing desktop that might hold you off from replacing it for another year or two. With four ports, you could also forgo a router, and wire point to point if that meets your requirements.
Review: It’s not bad just use with intel things - It could use a little more due to it having conflict with certain hardware

### ⭐⭐⭐⭐ Solution for "Forbidden Router"
*by C***S on February 4, 2025*

4 ports, each 2.5 GbE. These works fine in Linux, and hence in Proxmox. I have two of these cards running behind a pfSense virtualized router, and haven't noticed any performance or heat problems. Do make sure you have ventilation for the card, but I haven't noticed this card running especially hot. 2.5 GbE is the new 1 GbE in 2025, and should be the minimum now for household networks, especially if you want to take advantage of the new higher WiFi speeds.

### ⭐⭐⭐⭐ It’s not bad just use with intel things
*by R***R on June 3, 2025*

It could use a little more due to it having conflict with certain hardware

### ⭐⭐⭐ Tried extensively, could not get working on PFsense or OPNsense
*by M***L on December 10, 2023*

Some reviewers said they got it working. I'm beginning to think I had a broken card, but I spent HOURS trying literally everything on OPNsense and PFsense and this thing would not work. This was running in a VM. I tried so many things. I got interfaces to detect but all kinds of things wouldn't work past that. It might work on physical hardware, but I'd avoid this for VM use.
