  • October 2003 - Split Tunneling for Concurrent Access to the Internet and an Intranet

    When a Windows-based VPN client makes a VPN connection, it automatically adds a new default route for the VPN connection and modifies the existing default route that points to the Internet to have a higher metric. Adding the new default route means that Internet locations except the IP address of the VPN server are not reachable for the duration of the VPN connection. This article describes how to configure split tunneling, so that both intranet and Internet locations are simultaneously reachable.
