I've installed UTM 9 and while trying to set it up I've run into some problems. For some reason that I cannot figure out the WAN interface will not come [Up] when connected when I put my Comcast Cable Modem/Router into bridged mode. I have it set up with Type > Ethernet and and have the correct NIC selected for that interface, I also have the Dynamic IP box checked and the IPv4 default Gateway box checked.
Then when I disable bridge mode on my Modem/Router it then the WAN interface comes [Up] but it is issued a private IP address I am thinking that this will cause double NAT'ing which I don't want to do. Does anyone know what might be causing this to not work properly in bridged mode?
I've included two screen shots.
