Further complications arose from the fact that in many implementations the debug output was difficult to interpret, if there was any facility to produce diagnostic output at all. The following rfc 2409 were addressed: IKEv1 consists of two phases: Indicates the type of exchange being used. rfc 2409

IKE phase one’s purpose is to establish a secure authenticated communication channel by using the Diffie—Hellman key exchange algorithm to generate a shared secret rfc 2409 to encrypt further IKE rfc 2409. Are there other reasons besides the fields’ sizes for not using these groups? Implementations vary on how the interception of the packets is done—for example, some use virtual devices, others take a slice out of the firewall, etc.

An Unauthenticated Mode of IPsec. IKEv2 does not interoperate with IKEv1, but it has enough of the header format in common that both versions can unambiguously run over the same UDP port.

Main Mode protects rrc identity of the peers and the hash of the shared rfc 2409 by encrypting them; Aggressive Mode does not.
