Key Management

Key Exchange Method

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.
