Solution:

Use a VPS somewhere that will act as a proxy to your home server.

Connect the VPS to your home with wireguard/tailscale and do reverse proxy to your game server.

Now the public IP will be your VPS. Host it in an other close by country.

Of the IP does get flagged, change the VPS provider and keep the exact same setup.

You’re welcome ! I updated the documentation to cover some use cases with mobile devices using p2p sync or just relying on syncthing

Thanks for the feedback :)

Regarding mobile devices my plan on the short term is to integrate with Floccus.

In the meantime I have been using a workaround with Syncthing as following:

I have a folder synced between my mobile devices and gosuki. From time to time I export all the mobile browser bookmarks using the built-in export to html. On Gosuki you can setup the html-autoimport module which continuously watches the synced folder and imports the bookmarks. It works flawlessly.
