2/4 Why do classic VPNs fail?
1. **Blocked Ports:** Strict networks block everything except port 443 (HTTPS).
2. **Active Probing:** Firewalls connect to your IP, mimic client handshakes, and ban you if your server responds like a VPN.
3. **No UDP:** Corporate proxies block UDP entirely. Goodbye, QUIC/Hysteria.
Your VPN needs to look exactly like a standard HTTPS website, run on port 443, and pass active probing checks. Enter VLESS Reality.
