Chapter 16 VPN Screens
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 
). The ID type and content act as an extra level of identification for 
incoming SAs.
The type of ID can be a domain name, an IP address or an e-mail address. The content is the IP 
address, domain name, or e-mail address. 
16.9.1  ID Type and Content Examples
Two IPSec routers must have matching ID type and content configuration in order to set up a 
VPN tunnel.
