Hi. We are encountering the same problem as  Arjan van der Velde.
We also want to pass NFS traffic through our 10G/40G switches.

The difference is our VMs are in VMware ESXi with vmx(8) NICs (ie. VMXNET3).
Packets will not traverse our FreeBSD gateway unless they are under 4084 bytes.
We can ping jumbo packets to either of the vmx(8) NICs, but jumbo packets will
not pass through the gateway.

thanks for any attention/pointers.
P Kern
