Key Exchange Method

Management
The gateway supports both automatic and manual key management. When
automatic key management is selected, Internet Key Exchange (IKE) protocols are
used to negotiate key material for Security Association (SA). If manual key
management is selected, no key negotiation is needed. Basically, manual key
management is used in small static environments or for troubleshooting purposes.
Note that both sides must use the same key management method.
