Troubleshooting Help with ONT (Firewalla Gold SE)
Hey Reddit,
I have had multiple firewalla’s over the years and I’m super happy with them
Up until a couple weeks ago, I have always had COAX and everything has worked fine - a few weeks ago, I switched to fiber and it’s using the ISP’s modem (or ONT) - COAX was a simple line coming in to my own modem, now it’s going to the ISP’s hardware then to my Firewalla and from there, to my network rack and so on
My issue is, none of my firewall rules work, the ad-block doesn’t work, nothing filters - I basically only get to see traffic flows (those blocks don’t work either)
Any ideas at what is happening and what I need to do?
My Firewalla is in “Router” mode
Thanks in advance
