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?
Some ISPs will also let you switch to your own modem if you call them and set it up with them. Have done that for years with my ISP as they otherwise charge a rental fee for their modem that pays for a completely brand new modem after only 6 months.
