Setting up the L2TP WAN connection type on the Linksys LRT214 and LRT224

The Layer 2 Tunneling Protocol (L2TP) WAN connection type is a legacy feature originally designed for specific ISPs in Europe.  The legacy feature does not support advanced security options such as MPPE encryption and L2TP over IPSec.  Without the advanced security options, the current implementation on LRT routers cannot work with third-party VPN services that employ L2TP.
This article will guide you on how to set up the L2TP WAN connection type on the Linksys Gigabit VPN routers, LRT214 and LRT224.  Before you proceed, make sure you have completed the following in your L2TP Server:
