Description | Case Study: Using IPSec VPN as backup for Private WAN |
Introduction | When using a private WAN such as Frame Relay, ATM or dedicated point-to-point link, it may be desirable to use an IPSec tunnel(s) over the Internet to act as the backup in the event that the private WAN is inaccessible. This case study assumes you have a FortiGate 60 at both sites and that both sites have access to:
|
Steps or Commands | WAN2 (IPSec VPN) can act as a backup from WAN1 (private WAN). You need the following (on both ends):
If WAN1 is up (as defined by link status or ping server), the FortiGate unit routes traffic across WAN1. If WAN1 is down, the FortiGate unit forwards traffic across the VPN tunnel (on WAN2). Note: Fail-over and fail-back only affects new, not existing, sessions. |
