10.3 Establish VPN Connection Using Manual Keys

maintenance is more important or automatic keying is not feasible due to
interoperability issues between IKE implementations on the gateways. However,
this is a weak security option as all packets use the same keys unless you - as the
network administrator, use different key for authentication.
