16.6.8 ID Type and Content
With aggressive negotiation mode (see
), the ZyXEL Device identifies
incoming SAs by ID type and content since this identifying information is not encrypted. This
enables the ZyXEL Device to distinguish between multiple rules for SAs that connect from remote
IPSec routers that have dynamic WAN IP addresses. Telecommuters can use separate passwords to
simultaneously connect to the ZyXEL Device from IPSec routers with dynamic IP addresses

IPSec routers that have dynamic WAN IP addresses. Telecommuters can use separate passwords to
simultaneously connect to the ZyXEL Device from IPSec routers with dynamic IP addresses
(see
for a telecommuter configuration example).
Regardless of the ID type and content configuration, the ZyXEL Device does not allow you to save
multiple active rules with overlapping local and remote IP addresses.
multiple active rules with overlapping local and remote IP addresses.
With main mode (see
), the ID type and content are encrypted to
provide identity protection. In this case the ZyXEL Device can only distinguish between up to 12
different incoming SAs that connect from remote IPSec routers that have dynamic WAN IP
addresses. The ZyXEL Device can distinguish up to 12 incoming SAs because you can select
between three encryption algorithms (DES, 3DES and AES), two authentication algorithms (MD5
and SHA1) and two key groups (DH1 and DH2) when you configure a VPN rule (see
