Cisco Systems PIX515E quick start Configure the IKE Policy

Step 3 Configure the IKE Policy

This step is comprised of two windows:

1.Configure the IKE negotiation parameters.

In most cases, the default values are sufficient to establish secure VPN tunnels between two peers.

a.Select the Encryption (DES/3DES/AES), Authentication algorithms (MD5/SHA), and the Diffie-Hellman group (1/2/5) used by the PIX 515E during an IKE security association. Confirm all values before moving to the next window.

Note When configuring PIX 2, enter the exact values for each of the options that you selected for PIX 1. Encryption mismatches are a common cause of VPN tunnel failures and can slow down the process.

b.Click the Next button to continue.
