Intel NICs

[DCLR]

I plan to roll out a new OPNsense install on a surplus computer. I'll need one or more 4-port NICs (the machine only has 2 expansion card slots). The Intel I350T4V2 card has been highly recommended, but after seeing the price, I'm considering alternatives (Intel ONLY).

The PRO/1000 4-port card is a lot more wallet-friendly. Is there a substantial difference in performance between the two? I'm on a tight budget, but I don't want to buy the wrong thing and regret it.

Can anyone give me an unbiased comparison between the I350T4V2 and the 4-port PRO/1000?

Thanks!

Any mileage in a dual-port card? What is your use case for multiple interfaces? Would VLAN separation be an alternative? Managed switches are quite affordable.

 In my case, I need three ports for WAN—two for my primary provider (using LACP) and one for my backup. The 4th port is the LAN.

I’d prefer using single or double port cards, but the machine only has two PCIe card slots.

Basically someone asked for Intel version and dev said 2,5GBE Intel NICs have serious, not fixed bugs:

So what should I use for 2.5GBE for opnsense?

x550-t2 and x710-t2 - both support 2.5gbe ( as well as 5gbe and 10gbe )
