26.13.2 Telecommuters Using Unique VPN Rules Example
With aggressive negotiation mode (see section 26.10.1Negotiation Mode) the Prestige can use the ID types
and contents to distinguish between VPN rules. Telecommuters can each use a separate VPN rule to
simultaneously access a Prestige at headquarters. They can use different IPSec parameters (including the pre-
shared key) and the local IP addresses (or ranges of addresses) can overlap.
See the following graphic for an example where three telecommuters each use a different VPN rule to initiate
a VPN connection to a Prestige located at headquarters. The Prestige at headquarters identifies each by its ID
type and contents and uses the appropriate VPN rule to establish the VPN connection.
