Double NAT and DMZ

I have two routers set up in my house - the Hitron CGNM-2250 that Shaw provides and a Asus RT-N66U. Having both these machines up means that I have double nat, which makes it so that port-forwarding is difficult. To try and rectify this I've tried to set up a DMZ on the Hitron router and point it to my RT-N66U, but that hasn't seemed to work because none of my ports are being verified as open if I use an online port checker. I've set up a static WAN IP for my RT-N66U, an IP of which is outside the DHCP range of the Hitron (, the subnet is, and the default gateway is I point the DMZ Host on the Hitron to, which is the only connected device to the Hitron (as it should be, there's only one ethernet cable in the back)


Am I doing anything wrong? The ports aren't going through when I do it like this.


I was also recommended to try bridging my routers, but the representative said I'd have to go exchange my Hitron for a Cisco router (which I'm fine with) but it would remove my Internet 60 promotion package and revert it to a Internet 30.
