One of my client is using Fortigate100A firewall For their two companies connectivity using VPN(site to site connectivity).They already have the point to point leased line connectivity.
Note:Both the end, Internet and data leased line are terminating in
cisco 1841 router.VPN is done in Fortigate100A firewall.For Internet leased line am using static route and for data leased line am using Eigrp protocol.
I want to do failover between Private leased line and backup as VPN.
Can anyone help to configure this in Fortigate100A firewall.
