Review: Worked well with ProxMox hypervisor - I have a Dell T630 tower server running ProxMox. The NIC worked with OS native drivers - no custom driver installation was required. All I had to do was edit the /etc/network/interfaces file and now all the interfaces are available for use by guest VMs. Review: Works for pfSense 2.7 - 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.
