Open Settings → Mesh → Advanced. Most people never need to change these. On iPhone, changes apply the next time the mesh starts. On Android they apply right away.
Finder Relays
Your devices post where they are on these relays, so your other devices can find them. Like any relay, they see this device's IP address. Swipe to remove one on iPhone, or tap Remove on Android. At least one must stay.
Middle Server
The middle server links two devices that can't reach each other directly. It's how this phone reaches anyone outside My Devices: the photos of people you follow, a browser vault, and visitors to your home vault. They never get this phone's address, but the middle server does see it. Which follows' photos your app loads is up to you; who can see your photos isn't a setting.
- Public (fips1, fips2.iris.to): the default on iPhone. On Android the default is None, so pick Public for follows' photos, a browser vault and home vault visitors.
- None: only devices on the same network can connect. Follows' photos load from their web addresses instead, a browser vault only connects on the same network, and a home vault takes no visitors.
Reset to defaults puts both lists back.
