💡 Deployment Recommendations and Best Practices
Server Deployment: Can be deployed on personal VPS, home NAS, Raspberry Pi, or old computers; Tailscale and ZeroTier also support completely self-built dependency-free deployment.
Router Configuration: Prioritize enabling UPnP/NAT-PMP for automatic port opening; if not supported, manually configure port forwarding in router management backend.
Client Management: Create simplified client configuration files or QR codes for other users to quickly import, lowering usage barriers.
Performance Optimization: Choose protocol based on network latency and bandwidth; prioritize WireGuard for local networks, Tailscale for cross-domain networks, V2Ray for stealth requirements.
Security Hardening: Enable firewall rules to restrict access, regularly update server software, use strong passwords and keys, monitor abnormal connections.
