About this tag
IKEv2 (Internet Key Exchange version 2) is a VPN protocol used for secure tunneling and remote access. On WindowsForum.com, discussions cover its role as a modern alternative to deprecated protocols like PPTP and L2TP, with Microsoft recommending SSTP and IKEv2 for secure networking. Security vulnerabilities affecting IKEv2 implementations are also highlighted, such as CVE-2025-14733 in WatchGuard Firebox's iked process and CVE-2025-50156 in Windows RRAS. Troubleshooting topics include IPsec connection failures using IKEv2 tunnel mode on Windows 7 and Server 2008 R2, and the WAN Miniport (IKEv2) device appearing as non-functional in Device Manager. These threads reflect IKEv2's importance in enterprise VPN and routing scenarios.
