Usually, when a computing device using a VPN connection drops its Internet connection, the end user has to manually reconnect to the VPN once Internet connectivity has been restored. VPN Reconnect keeps the VPN tunnel open for a configurable amount of time so when Internet service is restored, the VPN connection is automatically restored as well. The feature was designed to improve usability for mobile employees.
VPN Reconnect, which requires the VPN server to be set up on Windows Server 2008 R2, uses the Internet Key Exchange v2 (IKEv2) tunneling protocol with a MOBIKE extension. MOBIKE prevents disconnected VPN clients from having to perform IKEv2 renegotiation once Internet connectivity with the VPN server has been reestablished.
VPN Reconnect can be used in conjunction with DirectAccess.
