I am having issues with slow speed on my wan interface. I have gigabit fiber, but my DL is only 50Mbit, with ~100Mbit upload. If I run iperf between a LAN PC and the OPNsense LAN interface, I get my 1Gb. If I run iperf from a machine directly connected to the "modem" to a public iperf server, I get pretty close to my 1Gb. If I run iperf from my OPNsense to a public iperf server, I get 50Mbit down, 120Mbit up.
I've googled a bunch, and made sure all the offloads are disabled, IPS/IDS are disabled. But I am not all that deep into actual system administration to know how to achieve the next bit, which seems to be to force my NICs away from the xn* to en1000 drivers.
How would I go about doing that? Any help is appreciated.

Just to test... try not using autonegotiation of speed and duplex on ports. Use fixed values.

I think I did #6 on this page to get it working for me.
