that’s exactly why.
Comment on Selfhosting static site behind two routers?
Onomatopoeia@lemmy.cafe 3 days agoProbably because the ISP modem/router has limited capability.
I’ve done 2 routers like this for years (out of laziness more than anything) because cable modem router suck from a capability standpoint.

Is the ISP device a cable modem or is it fiber?
You may be able to replace it

it’s fiber.

Do you have a username and password for PPP? You could replace the device with something with a SPF port
Another option is that you could turn off masquerading (NAT) on the Asus router. This may not work but if you have different IP ranges on each device theoretically it would avoid double NAT

The actual cable modem can run in passthrough mode though. Look up the model and find the docs. Should be a quick and easy change, or your ISP at least should able to change it. It would be absurd if not.

the ISP locked their router. I have to go the the ISP’s site, login and change settings there… can’t even change DNS on ISP-router.

That’s a bummer. Have you asked them about running it in passthrough mode?

No I haven’t. First i got to educate myself what these different modes are…
