Manual-key configurations Configuration overview Manual-key configurations This section explains how to manually define cryptographic keys to establish an IPSec VPN, either policy-based or route-based. The following topics are included in this section: • Configuration overview • Specify the manual keys for creating a tunnel Configuration overview You can manually define cryptographic keys for the FortiGate unit to establish an IPSec VPN. You define manual keys where prior knowledge of the encryption and/or authentication key is required (that is, one of the VPN peers requires a specific IPSec encryption and/or authentication key). In this case, you do not specify IPSec phase 1 and phase 2 parameters; you define manual keys on the VPN > IPSEC > Manual Key tab instead. If one VPN peer uses specific authentication and encryption keys to establish a tunnel, both VPN peers must be configured to use the same encryption and authentication algorithms and keys. Note: It may not be safe or practical to define manual keys because network administrators must be trusted to keep the keys confidential, and propagating changes to remote VPN peers in a secure manner may be difficult. It is essential that both VPN peers be configured with matching encryption and authentication algorithms, matching authentication and encryption keys, and complementary Security Parameter Index (SPI) settings. You can define either the encryption or the authentication as NULL (disabled), but not both. Each SPI identifies a Security Association (SA). The value is placed in ESP datagrams to link the datagrams to the SA. When an ESP datagram is received, the recipient refers to the SPI to determine which SA applies to the datagram. An SPI must be specified manually for each SA. Because an SA applies to communication in one direction only, you must specify two SPIs per configuration (a local SPI and a remote SPI) to cover bidirectional communications between two VPN peers. ! Caution: If you are not familiar with the security policies, SAs, selectors, and SA databases for your particular installation, do not attempt the following procedure without qualified assistance.
