Sorry for the dumb question and hopefully this is relevant enough to the sub. I have my own firewall and right now it connects to my ISPs provided home router over rj45, their router gets a fiber hookup to their network and it’s the only ISP device in my home. If I have a firewall with a fiber port, can I take the fiber to the modem and hook that straight to my firewall, or is there a reason I need their device?
I mean you can, an ONT is not a router, it’s essentially a media converter. I use my own router (and have for many years) and had no issues. The FiOS tech even ran a long Ethernet run in my basement to connect the ONT and my router in my rack when they installed service.
Is getting an ONT with Ethernet output normal? The comments were making me think that’s more of best case but maybe not standard.
It wasn’t standard previously, and if you have TV service I think it’s still inconsistent but the past ~5 years it seems to be more common that they are setup that way from the start. If you have internet only service, and a newer ONT (like less than 10 years old) it is the standard configuration and is how the self install guide tell you to hook up the “quantum gateway” router from Verizon.
You can always call and ask to have your ONT converted to Ethernet output if it isn’t already and as long as it supports it I haven’t heard reports of much trouble there. The very early ONTs though don’t support it though IIRC but those should be being replaced at this point anyways.
