Used to be easier in the DSL days. Hardware was easy to find. Then my ISP switched to VDSL and it became almost impossible to find better routers. Now I have a fiber link and the ISP's router is so bad but I don't really know if I can just buy a better one and connect the fiber to it. I've been told ISPs have remote access to the router and can update it remotely and deny access if it's been tampered with.

It's probably a wise decision to avoid consumer products in general but it's becoming harder every year.

Does your ISP router have DMZ hosting, where you can forward all packets at layer 2 or 3 to your own router behind it?

What would be the advantage of that? Unless you "own router" is basically VPNing everything past the ISP router? In which case it's not really clear why you need the "own router" part...

There are plenty of VDSL modems which can be interfaced with a router of your choice.

I couldn't find any years ago. Perhaps the situation has improved by now.
