[HECnet] Off Topic - pfSense on Hyper-V

The physical machine has three NICs. A Realtek one which is on the LAN and used to access the host for management purposes. A dual port Intel one (Intel PRO/1000 PT) which provides the LAN and WAN interfaces to the virtual machine.

I realise this is completely off topic, but I think this list has a lot of experienced networking people, so I am hoping someone might have a suggestion. I have pfSense running as my firewall at home, running on Hyper-V. In case you don?t know, it runs on FreeBSD. I have run it for a few years and really want to get it upgraded to the latest. But when I do the upgrade doesn?t work because every packet in the WAN interface seems to get lost, it just cannot send anything to the WAN. The LAN side is fine. I posted on the pfSense forums about this a long time ago. I got some questions about the MTU, but it was fine I was just wondering if you have any thoughts/suggestions/experiences? Thanks Rob
