VirtualBox + SoftEther v4.11-9506-beta = Win8.1 BSOD ?

[allenkk]

I just suffer random BSOD after install the SoftEther VPN server v4.11-9506-beta.
After tracing the debug memory dump,

The random crash is inside:
Realtek NDIS Driver Rt630x64.sys or
Virtual Box VBoxNetFlt.sys.

I have updated Realtek's driver and VirtualBox to the latest version.
The BSOD is still here.

Once I remove VirtualBox, the system crash is gone.
Not really sure what the root cause is.

I am now trying older SoftEther version and hope it can solved the issue.
Is there any suggestion for that?

The latest RTM version:
softether-vpnserver_vpnbridge-v4.08-9449-rtm-2014.06.08-windows-x86_x64-intel

It still encounters the same problem.
Still looking for the solution.

Is the Softether server inside or outside the virtual box guest ?
