PfSense Gateway Timing Out (Error 64-65)

[Soarin]

Hello,

A friend of mine is having problems with his pfSense, every 10-30 minutes the gateway goes down and all connections time out, I've disabled hardware checksum and TCP Offloading (and enabled it), the pfSense is a fresh install with no packages installed, simple port forwards for game servers, websites, SQL, and mail server.

However, the pfSense is under HyperV, with a direct line going into the firewall, it is on a static IP.
My friend has tried legacy drivers and default NICs for HyperV, no difference in the problem.

HyperV Version: 6.3.9600.16384
Physical NICL: QLogic BCM5709C Gigabit Ethernet (Default R610 NIC)
pfSense Version: 2.4.1-RELEASE
pfSense VM: gen1
Other VMs: gen2
Windows Server 2012 Datacenter edtion R2/ Hyper-V (2012)

Any help is greatly appreciated

One of our Cisco switche's ports were both giveing Tx errors out (bad packets), Annoyingly simply reconnecting seemed to fix this…
