Cisco FTD especially 1000 and 2000 series model firewalls is not at all a good option for remote office if you are planning to have DUAL ISP connection or High Availability. The firewall cannot be managed remotely in High Availability mode. if you have MPLS or private circuit running to remote branch , still you will have to loop management port to internal ports and create a vlan switch, its a very cucumber some method with alots of issues.
