That is correct the static IP addressing used by VM Business uses a GRE tunnel and means the Hitron cannot be in modem mode.

If you need the public IP address on one of your devices as opposed to only the Hitron, then you need the multi-static IP address option. The first IP address of the fixed range is on the Hitron you can put the second on your outer. In this mode the Hitron does not performa any form of NAT.

This is exactly what I do. Works with the older servers as well as the newly launched VMB services I have this config with the Hitron Chita with the Business Gig1 option.
