Strange Issue with OPNSense

[JodyOwens]

I am currently running OPNSense configured like multiple of the walkthroughs show online. After configuration, my speeds on my WAN interface (VirtIO) is almost identical to what I had with my bare metal install. The speeds on the LAN (VirtIO) interface are horrible. I have tried everything that I could think of to fix the issue. The one strange thing that I saw was:

ethtool --offload ens4f1 (WAN interface) generic-receive-offload off - fixing my LAN speeds, but cuts my WAN speeds in half. If I go and turn it back on, the WAN speed goes back to normal, but the download on the LAN download goes to almost nothing, but the upload is almost spot on. I would rather not pass my interfaces through to the VM if I don't have to.

What additional information could I supply that might help?

Can you post your /etc/network/interfaces file? What make/model of physical adapter(s) are you using? Is this all going to the same physical switch?

I reset the machine because I think it is related to the processors in the machine not being able to handle 8/8 network connection fully. I am thinking that it might work if I pass the physical cards to the VM, but I would rather not if possible.

I did install it under ESXI to see if it worked any better. I am getting the same issues with it.

I just installed ESXI to see if it had the same issues. Here is something VERY strange:

Windows VM - full speed 8/8
FreeBSD 14.2 - full speed 8/8
OPNSense - reduced speed to around half
