Content
When you select IP in the Local ID Type field, type the IP address of your computer 
in the local Content field. The ZyXEL Device automatically uses the IP address in the 
My IP Address field (refer to the My IP Address field description) if you configure 
the local Content field to 0.0.0.0 or leave it blank. 
It is recommended that you type an IP address other than 0.0.0.0 in the local 
Content field or use the DNS or E-mail ID type in the following situations:
• When there is a NAT router between the two IPSec routers. 
• When you want the remote IPSec router to be able to distinguish between 
VPN connection requests that come in from IPSec routers with dynamic 
WAN IP addresses. 
When you select DNS or E-mail in the Local ID Type field, type a domain 
name or e-mail address by which to identify this ZyXEL Device in the local 
Content field. Use up to 31 ASCII characters including spaces, although 
trailing spaces are truncated. The domain name or e-mail address is for 
identification purposes only and can be any string.
Remote ID
Select IP to identify the remote IPSec router by its IP address.
Select DNS to identify the remote IPSec router by a domain name.
Select E-mail to identify the remote IPSec router by an e-mail address.
Content
The configuration of the peer content depends on the peer ID type.
For IP, type the IP address of the computer with which you will make the VPN 
connection. If you configure this field to 0.0.0.0 or leave it blank, the ZyXEL Device 
will use the address in the Secure Gateway Address field (refer to the Secure 
Gateway Address
 field description).
For DNS or E-mail, type a domain name or e-mail address by which to identify the 
remote IPSec router. Use up to 31 ASCII characters including spaces, although trailing 
spaces are truncated. The domain name or e-mail address is for identification purposes 
only and can be any string.
It is recommended that you type an IP address other than 0.0.0.0 or use the DNS or 
E-mail ID type in the following situations:
• When there is a NAT router between the two IPSec routers. 
• When you want the ZyXEL Device to distinguish between VPN connection 
requests that come in from remote IPSec routers with dynamic WAN IP 
addresses.
Security Protocol
Pre-Shared Key
Click the button to use a pre-shared key for authentication, and type in your pre-
shared key. A pre-shared key identifies a communicating party during a phase 1 IKE 
negotiation. It is called "pre-shared" because you have to share it with another party 
before you can communicate with them over a secure connection. 
Type from 8 to 31 case-sensitive ASCII characters or from 16 to 62 hexadecimal ("0-
9", "A-F") characters. You must precede a hexadecimal key with a "0x” (zero x), which 
is not counted as part of the 16 to 62 character range for the key. For example, in 
"0x0123456789ABCDEF", “0x” denotes that the key is hexadecimal and 
“0123456789ABCDEF” is the key itself.
Both ends of the VPN tunnel must use the same pre-shared key. You will receive a 
“PYLD_MALFORMED” (payload malformed) packet if the same pre-shared key is not 
used on both ends.
Certificate
Click the button to use a certificate for authentication. Select the certificate you want 
to use from the list. You can create, import and configure certificates in the Security > 
Certificates
 screens.
