Centurylink Gigabit Fiber- Using my own router?

Hardware Hub Networking
1

I'm happy to have gotten on gigabit now, but would prefer to have my router (asus ac3200) connected straight to the ONT. If someone has had experience or knowledge of how this can be set up while keeping full functionality of Prism TV, I'd love to hear it. I tried before, but couldn't find stable settings, and the setup seemed to have broken the DVR functionality of the set up box. So I'm back to having my router sitting as a lan device off of centurylink's router.

What has your ISP said about you replacing the router they issued you with your own? Many ISP's are vehemently against it so you should call them. If they do not comply, connect your router to the ISP router then use it from there... Surely there is a better solution

I run my router off of our comcast router/modem combo and it works fine. You basically just put your own hardware between your machines and the ISP's hardware.

I am quite sure you don't have your Comcast router setup as your router,it is only being use as a device to connect to your isp. I the case of the op I don't think that's going to work. The op best choice is to contact his isp and explain very carefully what he is trying to do. It might be you need the isp equipment to access the DVD setup box.

Nope. The rest of my family connects to the comcast router itself for their needs (WiFi, NAS, work machines, TV, etc). I wired ethernet from it to my own router, using the comcast router as the gateway (I think that's the right terminology...?). That way I more or less have my own network with my own WAP that I can monitor at my convenience. This I should have clarified before. Whether this will work for OP though is another matter, as you said.

This.

And if you have to double NAT, try to enable the ISPs router's DMZ setting, and make it the IP that your router will use. The DMZ setting is essentially port forwarding on every port. ex: 192.168.1.2

One more thing, keep your private IP rages different (sub)network than what your ISP router uses.
ex: ISP router network lan: 192.168.1.0/24
your network lan: 192.168.69.0/24
and your WAN address would be: 192.168.1.2

That was how I thought your connection was working, in anther words your router is signing your ip address instead of Comcast router.

Thanks, DMZ seems to be good. conviently they are already on different ip ranges, provided router is on 192.168.0.x. Although the gui interface for my router still reports having an external IP as the internal one, I can confirm that ddns is working on it.

That's to be expected. The router doesn't care that it's a double NAT and that its WAN port is behind another LAN.

Sounds like you're well configured. If you ever have to do port forwarding, you should only have to do it on your router, not the ISP provided router.
