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.

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. ## Frequently Bought Together - IO CREST Quad 2.5 Gigabit Ethernet PCI Express PCI-E Network Interface Card 10/100/1000/25000 Mbps RJ45 LAN Realtek RTL8125 Chipset, Black (SI-PEX24077) - TP-Link 8 Port Gigabit Switch | Easy Smart Managed | Plug & Play | Desktop/Wall-Mount | Sturdy Metal w/ Shielded Ports | Support QoS, Vlan, IGMP and LAG (TL-SG108E) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.at/products/434747999-si-pex24077](https://www.desertcart.at/products/434747999-si-pex24077) --- *Product available on Desertcart Austria* *Store origin: AT* *Last updated: 2026-05-07*
