Working around lack of router settings (lemm.ee)

I am currently living with my parents and we have just started an Internet contract with a 5G wireless company.

The issue is the MFND settings are behind a password and likely not allowed access by the ISP. Even if they weren't doing port forwarding on 5G likely isn't possible because of CGNAT. I think I can use cloudflare tunnels or tailscale to get around this, and not many things need to be directly accessible from the Internet.

The more annoying thing is that setting DHCP reservations likely isn't possible without getting access to the settings. It's going to make setting up static IPs difficult too.

Before anyone asks fixed line Internet almost certainly isn't practical in this area. Getting our own modem while possible is more expensive and potentially difficult, and would mean cancelling the contract.

Is there a reasonable way to work around these issues?

Any help or advice would be appreciated.

Afaik tailscale will work with CGNAT and you can get your own router to sort out DHCP (or just pihole on your server?). Others can probably provide better answer

Wouldn't that cause a problem with two DHCPs being active?

Honestly I think someone else should answer this, but I believe you can just use different IP range (example 192.168.0.x on ISP device and 192.168.1.x on new router). Reading other comment it looks like its not the best idea, but we have that kind of setup in office and it works fine. There is no selfhosting involved tho

You don't use VLANs to separate traffic?

You connect them in a chain.
