Although being somewhat experienced in setting up P2P OpenVPN on OPNSense for some reason this time I can only get traffic 1-way. It's been a while since I've done this so I've probably missed something.

Meaning, Site A LAN cannot reach Site B's LAN, even though Site B's LAN CAN reach Site A's LAN.

The OpenVPN firewall rules are set up the same on both sites: IPv4* Allow everything from everything to everything.

Protocol    Source    Port    Destination Port   Gateway
IPv4 *    *    *    *    *    


OpenVPN Server Settings: (Site A)

Tunnel Net: 172.16.12.0/24
Local Net: 192.168.55.0/24
Remote Net: 192.168.54.0/24


OpenVPN Client Settings: (Site B)

Tunnel Net: 172.16.12.0/24
Remote Net: 192.168.55.0/24

There are no LAN rules on the Site B OPNSense other than the default LAN4/6 to Any.

If the other instructions in this thread don't work, you also need "set hint.ahcich.0.sata_rev=2"

I'm using an Intel NUC6CAYH and it would only boot by setting the following at the bootloader prompt:

set hint.ahcich.0.sata_rev=2
set machdep.disable_msix_migration=1
set hint.hpet.0.clock=0
set hint.ahci.0.msi=2
set hint.ahci.1.msi=2

Hallo,

set hw.sdhci.enable_msi=0
set hint.sdhci_pci.0.disabled="1"
set hint.sdhci_pci.1.disabled="1"

Funktioniert nicht mit Intel NUC

I'm having the same problem with 18.1.6 on an Intel NUC NUC6CAYH, using an SSD drive. Upgrading from 17 to 18.1 killed my firewall as a result, good thing I only do upgrades at night :)

Topuli's instructions worked for me as well. That said, being at risk of stating the obvious here, hopefully there will be a fix to the installer coming soon.

NOTE: I was only able to resolve ALL issues - including the HPET hang by issuing all these commands at boot:

@mossi2000

can you confirm that repeatedly? Would be really good news. I've been targeting xHCI for a while.

Hi,

This is happening to me now after upgrading from 17* to 18.1.6. Even a fresh USB reinstall I have the issue. Adding hint.ahci.0.msi="0"
hint.ahci.1.msi="0"
did not work..
