How to configure Comodo Firewall as a transparent "drop in " FW

I currently run Untangle UTM in “bridge” mode with both NICs bridged and one IP address (an address from my LANs range) to the two NICs. Is it possible to set up Comodo Dome Firewall like this so it is a straight drop-in between my ADSL modem and network switch? I don’t want to have to mess with the current LAN subnet configuration etc.
