I think I already know the answer, but I'm relatively new to the whole self-hosting thing so I wanted to ask.

I'm successfully self-hosting several things now, and just switched ISPs (went from DSL to fiber, very cool). My new ISP has me behind CGNAT or something similar, port forwarding and duckdns and the like that all used to work to access my homenet all no longer do. I called and asked them to get me off that. Only if I get a different plan at double the price. Oh, well. Not a huge deal to me, personally, I can still access everything important through Tailscale anyway.

My wife, on the other hand, is pretty tech-phobic. She had access to Overseerr from her phone previously, and no longer does because of the ISP switch. I could put Tailscale on my wife's phone, but there's a couple issues there and she'd honestly hate it.

Any alternatives that I can use for my tech-iffy wife to get around my ISP's irritating NAT?
