Review: Fan is quiet - I was concerned that the small fan on the card would be loud. I cannot even hear it in my OPNsense firewall situated in my Livingroom.
Review: I bought this network card to use in an OPNSense firewall/router machine i was building, I wanted to use one port on the NIC for 2.5gbe WAN and the rest for 2.5gbe LAN. I've been using this for a few days in my firewall and have had 0 problems since install, its been extremely stable. Before installing OPNSense on my machine, I tested the card out on windows and Ubuntu and it seemed to be working fine as well. I'm very satisfied with my purchase, i was reluctant at the lack of reviews but I've had a good experience so far, if anything changes I will update this review.

### ⭐⭐⭐⭐⭐ Review
*by A***T on 22 May 2025*

Was able to get this working for pfSense 2.7. You have to install the Realtek package. Try to do this prior to installation of the card or it’ll be impossible to get the packages (you need a working WAN port). 1. Enable secure shell in Advanced settings and SSH as admin to your firewall management address 2. Select 8 for shell and run “pkg install realtek-re-kmod” (the package installer will instruct you to do the following) 3. Edit boot “ee /boot/loader.config” 4. Add the two lines if_re_load=“YES” if_re_name=“/boot/modules/if_re.ko” 5. Save file by pressing ESC and answering leave editor and save 5. Reboot by typing reboot
