IKEv2/IPsec offers the best auto-reconnect capabilities for mobile users. Provide VPN access without requiring your users to download a third-party app.
IKEv2 connects natively via OS settings. No app required.
Allows the connection to survive network changes (e.g., leaving Wi-Fi to use 4G/5G) without dropping.
Supported natively by iOS, macOS, Windows, and Android. Perfect for corporate environments where installing apps is restricted.
Faster than OpenVPN and very CPU efficient, offering excellent throughput.
Uses fixed UDP ports (500/4500) which are easy for firewalls to detect and block compared to V2Ray or OpenVPN.
Manual server configuration is notoriously difficult. (However, VpnServerHub automates this entirely).
The "Mobility and Multihoming Protocol" (MOBIKE) is what makes IKEv2 superior for phones.
Unlike other VPNs that break when your IP changes (like walking out of your house), IKEv2 detects the network change and simply updates the tunnel path without disconnecting your session.
