Content When you select IP in the Local ID Type field, type the IP address of your computer
in the local Content field. The 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 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 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 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.
