4.4 Peer
What is ...
The Peer is a term that refers to the remote Security Gateway the IPSec secure 
tunnel(s) will be connected to. In a first phase, an IKE Security Association is 
negotiated between the SpeedTouch™ and a remote Security Gateway (peer). This 
IKE SA serves as a signalling channel for subsequent tunnel negotiations. 
In the configuration of the SpeedTouch™, the Peer bundles all the parameters 
required to negotiate an IKE Security Association (Phase 1 SA), such as:
Address
The public IP address of the remote IPSec peer. Eventually a backup address 
can be defined.
Local ID 
The identity of the local peer, which is presented to the remote peer during the 
Phase 1 negotiation. Various identity types are supported, such as: IP address, 
Distinguished Name. FQDN, etc.
Remote ID
Similar to the Local ID, this parameter identifies the remote peer during the 
Phase 1 negotiation. Various identity types are supported, such as: IP address, 
Distinguished Name. FQDN, etc.
Authtype
Authentication method used: preshared key or with certificates.
XAuth user and password
Allows for a secondary authentication based on a legacy authentication 
system
Descriptor
Refers to the Phase 1 security descriptor.
The Peer parameters are explained in 
How is it used
Peer can be successfully configured from the moment when a valid 
Authentication Attribute and a Peer Security Descriptor are present in the 
SpeedTouch™.
