Please could someone give me hand with this.

I have configured my BeBox to be bridged but do not understand what I need to do on my Draytek so that is acts as the router. I gather I need to put my Be static IP in somewhere but where?

You can't do that with the 2800 series, the only WAN interface on that is the ADSL2+ port, you'd need something like the 2820 or an ethernet router (29xx series) to use the BeBox as a modem/bridge.
