DESCRIPTION
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.
Type the WAN IP address or the URL (up to 31 characters) of the IPSec router
with which you're making the VPN connection. Set this field to 0.0.0.0 if the
remote IPSec router has a dynamic WAN IP address (the Key Management field
must be set to IKE).
In order to have more than one active rule with the Secure Gateway Address
field set to 0.0.0.0, the ranges of the local IP addresses cannot overlap between
rules.
If you configure an active rule with 0.0.0.0 in the Secure Gateway Address field
and the LAN's full IP address range as the local IP address, then you cannot
configure any other active rules with the Secure Gateway Address field set to
0.0.0.0.
protocol (RFC 2406) provides encryption as well as some of the services offered
by AH. If you select ESP here, you must select options from the Encryption
Algorithm and Authentication Algorithm fields (described below).
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.
