Self-hosting

I live in a rural aussie (with no fibre options) area with the worlds shittiest internet and especially bad upload. I been self hosting a bunch of things and simply just struggling through the shit connection.

Will be getting starlink to remedy the internet issue but it seems i need a business (priority) plan to get a public ip so i can access my services from the greater internet. This is however more expensive and i would like to avoid the additional cost if possible.

I was thinking i could wireguard proxy from my server at home to a cheap/free vps to bypass the restrictions but i suspect that would mess with how nginx on my home server manages ports etc. Plus i use my own hardware not just for security but also no recurring costs otehr than power so paying for a vps just to proxy seems like a waste.

Also been having dns issues with duckdns vos dynamic ip starlink seems not to support static ips so how should i resolve this issue.

Any advice or reccommendations?
