|
| 14 | +1. Display the public key. Send the key data portion to your peer. |

| 26 | +## Configuration |
|
| 27 | +### Configure the phase 1 IKE parameters |
|
| 28 | +In this example, we'll use the following settings: |
|
| 29 | + |
|
| 30 | +| Key | Value | |
|
| 31 | +| :------------ | :------------ | |
|
| 32 | +| Encryption | AES-128 | |
|
| 33 | +| Hash | HMAC-SHA1 | |
|
| 34 | +| DH Group | 5 (modp1536) | |
|
| 35 | +| Lifetime | 28800 seconds | |
|
| 36 | +| Peer address | 192.0.2.2 | |
|
| 37 | +| Local address | 192.0.2.1 | |
|
| 38 | + |
|
| 39 | +1. Add your peer's public key |
