11.17.2 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, the ZyWALL can use the ID types and contents to
distinguish between VPN rules. Telecommuters can each use a separate VPN rule to
simultaneously access a ZyWALL at headquarters. They can use different IPSec parameters.
The local IP addresses (or ranges of addresses) of the rules configured on the ZyWALL at
headquarters can overlap. The local IP addresses of the rules configured on the telecommuters'
IPSec routers should not overlap.
See the following table and figure for an example where three telecommuters each use a
different VPN rule for a VPN connection with a ZyWALL located at headquarters. The
ZyWALL at headquarters (HQ in the figure) identifies each incoming SA by its ID type and
content and uses the appropriate VPN rule to establish the VPN connection.
The ZyWALL at headquarters can also initiate VPN connections to the telecommuters since it
can find the telecommuters by resolving their domain names.
