Digi Connect?VPN Application Guide
Configuring IPsec VPN Using Pre-Shared Key
for Primary Connectivity
Scenario Digi Connect VPN is used for primary or backup remote site connectivity. Secured IPsec VPN traffic is typically routed from the Digi Connect VPN over the cellular IP network and is terminated by a VPN appliance at the host end.
There are several possible scenarios where the Digi Connect VPN can be used:
.. As the primary remote site router where no other WAN router is used.
.. As a backup router where the remote site has a primary WAN connection via DSL, Frame Relay, etc. If the primary router provides IPsec termination or origination then a Digi Connect?WAN or Digi Connect VPN can be used to pass VPN traffic through to the router. See the Digi Connect WAN application guide on using the Digi Connect WAN for Backup Connections.
.. To provide secure access to remote serial and/or Ethernet devices.
This document will focus on using the Digi Connect VPN as a primary remote site router using IPsec ESP and IKE/ISAKMP pre-shared key VPN.
