Intel I350T esxi vt-d passthrough problem

[segobi]

Hi,
im running pfsense 2.1.5 on esxi. Today I tried to pass through my 4 Intel I350 Nics. Pfsense sees them and uses igb Driver.
However I can not get any Connection (ping Fails etc.).
Passthrough seems to be working fine on Window Server 2012 R2 and also on Linux mint 17 (both running also on the same esxi Server).

Maybe someone has an idea and can help me ? Tia!

ok this should be in the virtualization section. sorry.
Its working now when i reboot pfsense - i read about this in another thread. Is there any solution to booting pfsense "twice" ? This machine is running 24/7 so its not such a big problem and pfsense isn't rebooted very often.
