Good point about interleave. However I also have the static IP subnet option, which means the Superhub forms an L2TP tunnel to the VM network in Birmingham (I am in Surrey), so my breakout point on the internet is Birmingham, so that will add some latency. Interleave would affect it too as you say.

What I have is a Cisco router behind the Superhub. Since I have a routed subnet the Superhub is not performing any NAT, so that is done on the Cisco 892W I have behind it. On the WAN interface of that router I have the ip mtu set to 1460 and my delayed email issue has gone away.

I had understood that a future firmware release for the business superhub will add modem mode. However I am not sure if the formation of the L2TP tunnel comes from the router or modem side of the Superhub. If the router side it would likely not be viable for the static IP options.

Current business superhub firmware is: V5.5.2R04-BU which is the same base as the residential version. I wonder if this means it's derived from R04 of the residential firmware!
