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.
