Weird issue with OPT1 internet access

Yes, that's your hardware NIC. But can you try to reconfigure your pfsense virtual machine to use a different nic-model/type? (not sure if that's possible but I'd think so)

That way it won't use the XenTools/virtual nic.

simple search here on pfsense forums for xenserver would of pointed you to many threads with pointing out the checksum problems.

There is even a Sticky in the VM section
