[Openstack-operators] Neutron firewall blocking GRE

Does anyone know if there is any reason I'm having trouble getting GRE traffic into my instances?
I have a router out on the internet an I'm trying to build a GRE tunnel into an instance to link a site office to my Openstack network, but looking at packet dumps from inside the VM I can't see any GRE packets making it in at all?

Regards,
Cory
