Yes you can bypass the gateway altogether.
I do this directly from the ONT into UDM-Pro/SE with a few customers and it works great.
Can’t recall for certain off the top of my head, you may need to get IP details or other info from Frontier to plug in to your own router… PPPoE perhaps…
I’ll dig into a customer’s config and get back to you.
Where do the STBs coax lines connect to the coax feed from the road? Surely the Frontier Gateway isn’t acting as a coax splitter…
Oh, I may have misunderstood. The coax that goes into the optical to rf converter is the one that comes from the pole outside, at least I’m almost certain. I think the coax to the gateway is just to some splitter ran outside, it’s really baffling
I would check on the Frontier forums, might have more people familiar with the TV side of things over there.
As for the Internet, you don’t need the gateway, just credentials for PPPoE
I have my pfsense connected directly to the ONT and have internet access through PPPoE. You need to know your account username and password from your ISP
I got rid of their gateway a long time ago and just plugged my router directly into the Ethernet cable from the ONT
Should be an Ethernet cable… At least that’s what mine uses. Might be able to run an Ethernet cable from the ONT into where your router is, if they didn’t use the Ethernet cable. if it’s missing the Ethernet port, maybe a new ONT box too? That’s at least my setup…
