Telnor(Mexican ISP) Fiber Passthrough or Seperate Router with ONT

Has anyone ever gotten a secondary router to work? In theory I should be able to enable Passthrough and use PPPOE to log in and use my Wi-Fi 7 router. They give me a user name and password, it doesn't work. I managed to hack and get the username and password the router with ONT they have and that doesn't log me in either.

These geniuses solution is to "buy one of our overpriced, crap Wifi6(which they claim is the newest and best) and it'll work." Given that passthrough doesn't work on my router, it won't work on theirs.

I even tried it. Passthrough didn't work. Only option that works ends up with double NAT, even if I set static IPs and a DMZ to my internal router..

Has anyone gotten this to work with Telnor. Or is there some option that if I can't get their genius techs to get it to work that involves static IPs, maybe a DMZ and routing?

Their best ONT/router has Wifi 5. I ask for one with at least 802.11ax/6 or 6E and they look at me like I'm crazy. I'm debating trying it one more time then using the threat of cancellation to get sent to a higher tech.

Worst case I cancel and go to Izzy, the cable company. At least with them, while they may not have the latest DOCSIS on their modems, and I can't remember if they allow third party modems - I can at least use a decent router and not some Wi-Fi 5 that is ancient.
 
Check with them if their PPPoE login require VLAN tagging - some fiber ISPs do.

I'm almost positive I've tried that. It was like 81 or 8081 or something. I vaguely remember it.

They definitely didn't know what I was on about. I'll try again when I get home though

You need to get that information, it will never work if you don't configure that properly, so that's the very first thing that need to be resolved. A quick web search indicates that the VLAN may vary between regions, but the most commonly mentioned one for your ISP is 881. So, you have to configure the correct VLAN for your WAN interface.
