I have Fiber Optic from AT&T which came with a Router/Modem (BGW320-500) and seperately purchased a Deco Mesh Wifi System (XE 5300). AT&T provides a modem/router, so I have tried to "IP passthrough" the IP address to my Deco Mesh Router so that I can setup a VPN server on the Deco Router to connect to Blue Iris. Ultimately my Deco Router will be providing internet to my Blue Iris Server.
This is where nothing works. I login to my AT&T router/modem and go to "IP Passthrough", select "DHCPS-fixed" and then select my Deco Mesh Router, since its the only device connected to my AT&T Modem/router. I restart my AT&T modem/router and the Deco Router. I login to my Deco Router and check the IP Address on the Deco Router. It still lists a private IP Address (192.168.X.X.) and is not passing through the IP Address from AT&T modem/router. I've tried hard restarting the devices, creating new networks, everything and nothing seems to work. I go to my Deco device and notice that the last digit of its Mac Address is different that what AT&T says. Instead of ending in "C1", Deco says its ends in "C0". So i go to the IP Passthrough and manually insert the Mac Address with C0 and then restart all devices. Still nothing works.
What the hell am i doing wrong?
