WebOct 20, 2024 · IPsec VPN configuration requires you to choose a Diffie-Hellman (DH) group, which is used in both phases of the IKE negotiation to securely communicate private keys between endpoints over an untrusted path. DH Groups 19-21 represent a significant increase in security over groups 14-16 and consume fewer resources during encryption. Webcrypto isakmp policy group1 Group 1 (768-bit) Specifies the Diffie-Hellman group identifier, which the two IPsec peers use to derive a shared secret without transmitting it to each other. With the exception of Group 7, the lower the Diffie-Hellman group no., the less CPU time it requires to execute.
