Starlink supports IPv6 addresses, I'm sure it would help. My network infrastructure is just lacking general IPv6 support, as I've not cared to get it set up in great detail, and my testing has demonstrated that my IPv6 addresses behind my router are publically reachable, so... I'll get around to proper firewalling at some point.

I could do a range of things to solve it, but as I have two ISPs, I typically just switch to the one that works better for the solution. I'm aware it's not a technically fancy solution, but it's quick and easy (change the gateway on the machine), and works fine.
