I have a TP-LINK TG-3468 PCIe NIC as my WAN adapter for pfsense. I had to switch the VirtualBox "Adapter Type" for that NIC from Intel PRO/1000 MT Desktop to Paravirtualized Network (virtio-net). From what I have read in the VirtualBox documentation the Paravirtualized Network (virtio-net) adapter type is special in that it doesn't virtualize the network hardware when it is already supported out of the box by the guest OS. (https://www.virtualbox.org/manual/ch06.html#nichardware) In any case, after making that change, pfsense worked like a champ! I guess I'll see if it has any ill effects as I begin to get deeper into pfsense. Thanks for all your help yarick123 and point me down the right path. ;D

I decided to try installing pfsense on Hyper V on Win 10 Pro and I got a HUGE boost in speed. I seem to get around 600 Mbps download and 900 Mbps upload. My understanding is the loss in upload speed is in the normal range, but the download still seems like abnormal loss (but far better then the 90% loss before), as soon as I take it off pfsense it is always 900 Mbps+. I just can't find what is bottlenecking. Is there anything for me to check in that range? I also think its really weird that now I have upload working pretty normally, and download is experiencing a 300 Mbps loss. I'd also prefer to use Ubuntu as the host system, if anyone has any ideas on why Virtualbox performance is sooo atrocious on reasonable hardware?

But in this case the ppp connection should be configured for the interface. You did not say anything about it. Have you configured ppp[oe]?

Don't mind if anyone gets the same issue at least they might benefit from what i did, .. Did pci passthrough basicly the same result, .. Tried to see if it was related to only pfsense installed opnsense same result, .. Made lagg0 of 4 pci gbit nic same result, .. not tested this senario on opnsense though. I've got the impression there's some sort of bottleneck, .. not quite sure if it's vtnet related.

What are you gaining by using NIC passthrough??  The vNICs have worked well for me for years.

OK, that is good to know. I seem to recall reading that performance (or something) was better with vmx. However I will switch if that's what it takes for reliability.

I think some questions are funny and some answers are funny and that not every post that lands here is as serious as you might like. But you are entitled to your feelings, so have at it.  Come on - Disabling both IPV4 and 6?  Its a little funny…. Not every reply to every mistake I ever made was serious either and I managed not to lose my cool. That said, I just joked because you already answered the issue.

I have come accross the same thing. The problem i have is when pinging the 2 carp boxes ping is fine.  When i ping the virtual ip address i get ping drops.] I'm struggling with vmware and pfsense. Mat

Is there anyone who has got this working?

Any resolve on this? I got the same issue

Hello, Did you had success install on Softlayer/Bluemix env? best regards, Carlos

Derelict your Xen NIC step seems to have fixed the issue. It looks like it is working perfectly now, thank you. Thank you as well KOM for you assistance.

If your hypervisor crashes, that is 100% a problem with your hypervisor or hardware. A problem in the guest OS should never cause the hypervisor to crash.

Thanks very much for the reply.  I did that and it's working fine.  Very happy with how this is running as a VM.  Much better than when I tried the x86 version on 2008R2 with its legacy adapters and all. Seamless install and config restored from my old 32bit box and everything works great.

What type of throughput did you see on this setup? I'm looking at doing something similar.

You are suggesting to migrate to another virtualization platform just in order to get some disk space? There must be an easier solution, right? Edit: Of course there is. Removed the disk in KVM guest, removed the underlying lvm logical volume and started over from scratch. Works now very well. Used this howto: https://www.freebsd.org/doc/handbook/disks-adding.html

Hi. In a past I'm using Xen as hypervisor too. But Proxmox VE (kvm hypervisor) more and more better. P.s. Even Amazon migrate to KVM.
