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 192.168.0.208 which is outside the DHCP range of the Hitron (192.168.0.10-192.168.0.200), the subnet is 255.255.255.0, and the default gateway is 192.168.0.1. I point the DMZ Host on the Hitron to 192.168.0.208, 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.
