his setup provided multiple NICs to the pfsense system, they would all be Hyper-V simulated NICs.<o:p></o:p></span></font></p>

similar issue with my Sophos UTM9 software appliance running on Ubuntu (a quad gigabit Intel chipset card) - The numbers of packet errors would keep climbing up very fast. I switched to a Broadcom and that worked. <o:p></o:p></span></font></p>
