Can't enable cascaded router on BGW320-500

The option for Cascaded Router is set to off, and is not editable on my BGW320-500. How do I fix this?

That would depend on how you want your router to be presented with the Public Static subnet.  

If you want your router to have a single Public IP from the static subnet and to NAT all the devices behind it to that Public IP, then you want Public Static Subnet mode, and assign your Router's WAN IP to one of the 5 useable Public Static IPs.

On the other hand, if you want your router to router for several different devices having different IPs from your Public Static Subnet, then you'll want the Cascaded Router feature. Program your router to have the Router (.6) address on its LAN and to deal with the 5 Useable Public IPs on its LAN (or, if you know how, you can configure it to NAT to them).  Your router would normally retain a Private IP from the Gateway's Private LAN range.

Why do you want to use cascaded router?

Why does the reason I want to use it matter?

Cascaded router being on may not be the correct setting depending on what you are trying to accomplish. Factory resetting the gateway may enable turning it on.

Hi tonytx05, we'd be happy to assist you with enabling cascaded router on your gateway.

 

Please let us know if you tried browndk26's suggestion to factory reset the gateway. Letting us know why you want to use this feature can help us make sure it's the best option for you.

 

The cascaded router feature is only used when a block of static IPs has been purchased. Otherwise, most customers just set up IP Passthrough.

 

We'll be awaiting your response!

@ATTHelp I have a block of static IPs, with my own router handling my network, hence the desire to enable cascaded router.

If performing a factory reset didn't help, tonytx05, setting up IP Passthrough is the best option.

 

You can also reach out to the team at our paid service, HomeTech to see what they recommend. They provide 24/7 support for a wide range of networking matters, including connecting third party equipment and gateway troubleshooting.

 

If you have questions about anything else, just let us know.

Resetting to defaults did nothing. The option for cascaded router was editable only when Public Subnet Mode was set to OFF. When I set it to ON and entered my Public Gateway/Subnet info, the Cascaded Router option was no longer editable.

You cannot enable cascaded router when you already have Public Subnet enabled.  It's an either/or choice.

If you would be willing to explain what you're trying to do, maybe we can help you set up appropriately.

So, if I have my own router setup behind the AT&T router, with a public static IP, which SHOULD I be using?
