IKE Peers Definition
IKE peers are those devices known to your internal modem as capable of participating in IKE connections. To
define a new IKE Peer:
1. Click Create next to IKE Peers from the Advanced IKE/IPSec Setup page. This displays the IKE Peer
Definition page.
2. In IKE Peer Name, enter a logical name for an IKE Peer. This name is of no importance to the remote IKE
peer. Choose a name that is meaningful to you.
3. In Pre-shared Secret, enter a case-sensitive character string used for authentication. This secret can be
up to 256 characters, with no spaces or non-printable characters. The pre-shared secret must be mutually
agreed upon by both parties to the IKE connection.
4. In Peer Gateway IP Address, enter the IP address of the gateway at the remote end of the IKE
connection. If the remote IKE peer does not have a fixed or permanent IP address, enter “0.0.0.0” to use
Aggressive Mode in Phase 1 negotiations. (Your system supports two Phase 1 IKE modes: Main and
Aggressive. Use Main Mode when both the source and destination IP addresses are known and use
Aggressive Mode when either the source or destination IP addresses could change.)
5. Click Apply.
