16.6.11.1 Telecommuters Sharing One VPN Rule Example
See the following figure and table for an example configuration that allows
multiple telecommuters (A, B and C in the figure) to use one VPN rule to
simultaneously access a ZyXEL Device at headquarters (HQ in the figure). The
telecommuters do not have domain names mapped to the WAN IP addresses of
their IPSec routers. The telecommuters must all use the same IPSec parameters
but the local IP addresses (or ranges of addresses) should not overlap.

16.6.11.2 Telecommuters Using Unique VPN Rules Example
In this example the telecommuters (A, B and C in the figure) use IPSec routers
with domain names that are mapped to their dynamic WAN IP addresses (use
Dynamic DNS to do this).
With aggressive negotiation mode (see Section 16.6.6 on page 234), the ZyXEL
Device can use the ID types and contents to distinguish between VPN rules.
Telecommuters can each use a separate VPN rule to simultaneously access a
ZyXEL Device at headquarters. They can use different IPSec parameters. The local
IP addresses (or ranges of addresses) of the rules configured on the ZyXEL Device
