Deletion of this directive fails. If the configuration applied has an error it will cause all VPN directives to disappear from the running config next boot. VPN directives still exist in saved config, but will not be applied. VPN directives can also not be modified until the bad configuration file is removed by hand or /etc/ipsec.conf edited by hand, and the system reboots.
