VPN Screens 14-37
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.
