      Hi,

      I recently modded my old 6th gen Intel NUC core i5 by adding a M.2 to GigE adapter (yeah I know Realtek isn't the best but this is what I got). So of course now with 1 Intel and 1 Realtek, what are your recommendations for WAN/LAN assignments and why?

      My use cases:
      NUC is used as the main home router to a gigabit fiber connection. I have 3 concurrent OpenVPN clients and 1 OpenVPN server with Suricata IDS/IPS running in legacy mode filtering and blocking some unwanted traffics on the LAN side (WAN I just have some FW rules to block the things I don't want).

      Currently I have my Realtek assigned as LAN and my Intel assigned as WAN, not sure if this is optimal or should I switch it the other way around? Oh and I installed the latest realtek kernel driver, so it's not running the stock version due to instability with stock drivers on Realtek.

      Thanks in advance!

        I doubt there is any difference. Traffic must pass from both.
        Newer realtek drivers work better too.

          I'd suggest to use Intel for LAN, especially if you need VLANs.

            @psp thanks for the reply! Can you elaborate the VLAN with Intel/Realtek? I don't have any VLAN right now but I'm might venture into that area later on, just wondering why Intel is better at VLAN?

            Thanks!

              Under FreeBSD, Realtek are just fine if used with recent drivers.
              Intel NICs are generally able to handle (considering the hardware+drivers features) better "complex" traffic (i.e. VLANs, traffic shaping, high speed connections).
              This is why I prefer to use Intel NICs on LAN (assuming that WAN is simply linked to an upstream router).

                @psp thanks for the advice. Yes, the WAN connection is just connected to the Fiber ONT. The LAN side is connected to a managed 16 port gigE switch which supports advanced QoS and VLAN configurations (not used at this moment). I have bunch of IoT devices running all on the same home network, so I'm planning to create a VLAN to segregate the IoTs from rest of the PCs/Mobile devices at home.

                  @faux123 And then you want to experiment with rate limits and bufferbloating, so you are better off with intel on the wan. :)
                  realtek with recent drivers do work fine though, so vlans are not an issue with realtek too.

                    @netblues Yeah, you are right, I have limiters and traffic shaping setup at this moment because Bufferbloat is a huge issue for me.

                    Thank you for your input.
