We are an ISP and provide our own home gateway to the subscribers, which
ends up routing traffic of a large range of end user devices.

In that case, the frag+DF traffic was seen in an exchange between a
femtocell and a femto GW during the IPsec IKE exchange, more precisely
on the IKE_AUTH message sent from the femto GW.

You can contact me privately if you need more details.
