Luna Display Network & Security on Shared Computers

Quick answer: Before using Luna Display on a work or school computer, check with your IT team. Disable any VPN, have firewalls whitelist Luna & Bonjour, disable client isolation, and grant screen‑recording permission. If Wi‑Fi is unreliable, use a direct cable or Peer‑to‑Peer mode (macOS 10.15 or later only).

If you’re using a company‑provided computer, check with your IT department before setting up Luna Display. Corporate security measures like VPNs, firewalls, and network isolation can block Luna’s connection.

VPNs

VPNs reroute traffic and hide local IPs, so Luna can’t discover your host. Disable the VPN when using Luna. A wired link (USB‑C, Ethernet, or Thunderbolt) can sometimes bypass VPN interference, but some VPN policies may still block Luna.

Firewalls

If Luna can’t connect, ask IT to whitelist:

Luna Display Primary & Secondary
Apple Bonjour (mDNS)
Astropad processes

Network Isolation & Device Siloing

Some enterprise networks block peer‑to‑peer LAN traffic. Ask IT to disable client isolation or create an exception for your devices’ IP addresses.

Screen‑Recording Restrictions

Luna uses OS screen‑capture APIs. Corporate policies that disable screen recording will break Luna. Have IT grant screen‑recording permission under macOS System Settings → Privacy & Security → Screen Recording.

Note: Luna Display never stores or records your screen content; everything is live‑streamed over your local network.

Public Wi‑Fi Networks

Hotel, café, and campus hotspots often block device communication. If you run into issues:

Use a direct cable (USB‑C, Ethernet, or Thunderbolt) between devices
Enable Peer‑to‑Peer mode (Mac‑only; requires iPadOS 13+/macOS 10.15+)
