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
Section 19.12 on page 320). 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.

E-mail Type an e-mail address (up to 31 characters) by which to identify this ZyWALL.
The domain name or e-mail address that you use in the Content field is used for identification purposes
