Shadow uses thousands of ports on your local network to send and receive data, providing a greater chance at securing a stable connection with low latency. Blocking any necessary ports can congest your connection to any of Shadow's data centers, causing high latency and even packet loss.
To make your local firewall compatible with Shadow:
- Open ports 8001 to 11299.
- Apply this rule to both TCP and UDP connections.
- Apply this rule only to outbound connections.
📝 Note: If your internet connection is provided by work, school, or another business, contact the local administrator for assistance.
