Chapter 15 IPSec VPN

Table 68 Security > VPN > General > Rule Setup: IKE (Basic) (continued)

LABEL	DESCRIPTION
Peer 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 NBG-460N will use the address in the Secure Gateway
	Address field (refer to the Secure Gateway Address field
	description).
	For Domain Name 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 Domain Name or E-mailID type in the following situations:
	• When there is a NAT router between the two IPSec routers.
	• When you want the NBG-460N to distinguish between VPN
	connection requests that come in from remote IPSec routers with
	dynamic WAN IP addresses.
IPSec Algorithm
Encapsulation	Select Tunnel mode or Transport mode from the drop-down list box.
Mode
IPSec Protocol	Select the security protocols used for an SA.
	Both AH and ESP increase processing requirements and
	communications latency (delay).
	If you select ESP here, you must select options from the Encryption
	Algorithm and Authentication Algorithm fields (described below).
Pre-Shared Key	Type your pre-shared key in this field. 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.
