Chapter 15 IPSec VPN 460N's LAN interface. Remote management must also be configured to allow HTTP access on the NBG-460N's LAN interface. Figure 125 VPN for Remote Management Example 15.6.2 IKE SA Proposal The IKE SA proposal is used to identify the encryption algorithm, authentication algorithm, and Diffie-Hellman (DH) key group that the NBG-460N and remote IPSec router use in the IKE SA. In main mode, this is done in steps 1 and 2, as illustrated below. Figure 126 IKE SA: Main Negotiation Mode, Steps 1 - 2: IKE SA Proposal 1 2 The NBG-460N sends a proposal to the remote IPSec router. Each proposal consists of an encryption algorithm, authentication algorithm, and DH key group that the NBG-460N wants to use in the IKE SA. The remote IPSec router sends the accepted proposal back to the NBG-460N. If the remote IPSec router rejects the proposal (for example, if the VPN tunnel is not configured correctly), the NBG460N and remote IPSec router cannot establish an IKE SA. Note: Both routers must use the same encryption algorithm, authentication algorithm, and DH key group. See the field descriptions for information about specific encryption algorithms, authentication algorithms, and DH key groups. See Section 15.6.3 on page 208 for more information about DH key groups.
