Configure a GRE over IPsec VPN with Manual Keying
9. Configure Authentication settings. These settings must match those on the
remote tunnel gateway exactly. Do one of the following:
•For Ty pe , select None.
•For Ty pe , select Simple.
i. For Password, type a password.
•For Ty pe , select MD5.
i. For Key ID, type the authentication key ID (1-255).
ii. For Key, type the 16-digit md5 key.
10. Click OK.
11. Click Save.
Move on the next task: creating an IPsec proposal.
Create an IPsec Proposal
Each IPsec proposal specifies the following:
■ IPsec mode (tunnel or transport)
■ IPsec security protocol:
• AH and a single authentication algorithm
• ESP, a single authentication algorithm, and a single encryption
algorithm
You can configure multiple IPsec proposals. In a later task, you will specify a
proposal in an IPsec policy. The algorithm or algorithms in that proposal will
secure traffic that is part of IPsec tunnels (VPN connections) that are estab-
lished with that policy.
Follow these steps to configure an IPsec proposal:
1. In the left navigation bar of the Web browser interface, click VPN > IPsec.
2. Click the IPsec Proposals tab.
