Title: Moving from Arista (Untangle) to Opnsense NIC Question
Post by: snakeyes75 on June 21, 2025, 05:23:54 PM
HI all,

I am looking to move from Arista to Opnsense soon.   I am running Arista on a i3 Dell Optiplex with 16 GB RAM and 128 SSD with a quad 2.5G nic (RTL8125).   I created a bootable USB with opnsense to see if it would work.  I ran the system in live mode, but it does not detect the quad nic, only the builtin Intel onboard network card.  I attached an USB Ethernet to see if I can install the drivers for the quad but no luck.   This is the card that I have https://www.amazon.com/dp/B09SS8GVHC?ref_=ppx_hzsearch_conn_dt_b_fed_asin_title_1&th=1 (SI-PEX24077)   Does anyone know if this can work with Opnsense?  I

Both Realtek and USB cards are badly supported with FreeBSD. There is a plugin with a Realtek OEM driver, but you will have to install it first, which is tedious without a working network connection in the first place.

Also, even the OEM driver is not guaranteed to work.

Does the Optiplex really have no single Intel card?

It has a working Intel 1G port.

Then you should configure that as the LAN and use your exiting router to get internet access to install the Realtek driver plugin and test if it works for you.

After the update and installing os-realtek-re ;  it found the quad network card.  I have to look at all the devices I reserved IPs for and the rules that I have setup and in sometime in July I will fully start using this instead of untangle.
