Setting Up an L2TP/IPsec Remote Access VPN on EdgeRouter X

Introduction In the previous article, Running an AWS Lambda + Route 53 DDNS Client on EdgeRouter X , I built a system that periodically runs a DDNS client on the EdgeRouter X to keep a Route 53 DNS record in sync with the global IP address assigned to its WAN interface. This made it possible to associate an FQDN with the dynamically changing global IP address. In this article, I use that setup to connect to the EdgeRouter X via remote access VPN.
