12.9 ID Type and Content

With aggressive negotiation mode (seeSection 12.12.1 on page 194), 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 (seeSection 12.18 on page 202 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.

With main mode (seeSection 12.12.1 on page 194), 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

(seeSection 12.13 on page 195). 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.

Table 74 Local ID Type and Content Fields

LOCAL ID TYPE= CONTENT=

IP Type the IP address of your computer or leave the field blank to have the ZyXEL

Device automatically use its own IP address.

DNS Type a domain name (up to 31 characters) by which to identify this ZyXEL Device.

E-mail Type an e-mail address (up to 31 characters) by which to identify this ZyXEL

Device.

The domain name or e-mail address that you use in the Content field is used for

identification purposes only and does not need to be a real domain name or e-mail

address.

Table 75 Peer ID Type and Content Fields

PEER ID TYPE= CONTENT=

IP Type the IP address of the computer with which you will make the VPN connection

or leave the field blank to have the ZyXEL Device automatically use the address in

the Secure Gateway field.

DNS Type a domain name (up to 31 characters) by which to identify the remote IPSec

router.

E-mail Type an e-mail address (up to 31 characters) by which to identify the remote IPSec

router.

The domain name or e-mail address that you use in the Content field is used for

identification purposes only and does not need to be a real domain name or e-mail

address. The domain name also does not have to match the remote router’s IP

address or what you configure in the Secure Gateway Addr field below.
