Above are the custom tunables I set for an Intel N6005 mini PC that has four Intel i226 NICs and is running OPNsense 23.1.11. I've copied them from a configuration export (these weren't all items inside the
<sysctl>
block), but you can manually set them via the System -> Settings -> Tunables section.Some more settings:
conservative
.Interface configuration (depends on your ISP; I'm using KPN fiber in The Netherlands):
I have absolutely no issues getting around 940/940 Mbps through the PPPoE interface (to the outside world), which is the limit because the fiber NTU only has a Gigabit Ethernet port.
