Hi Jggimi,
1. Backup means another OpenBSD IPSEC VPN Gateway ( New Machine ) to use in case of a failure of the running (Live ) VPN gateway. This backup is configured and kept aside to use in case of a failure.
2. Didn't work meant, when I copy the ISAKMPD folder from the live IPSEC VPN Gateway machine to the New backup Machine and when I connect the Backup IPSEC VPN Machnine to the ISP line by disconnecting the live IPSEC VPN Gateway, My VPN tunnel didn't connect
.
Thanks
