Remote Gateway IP or Host Name: the public IP address or host name of remote VPN device. For
example, it may be jet.dyndns.org (If remote IP is not fixed.) or 210.243.142.29.
Remote Subnet: The IP subnet of remote LAN environment, network ID. For example, it is 192.168.4.0
Remote Subnet Mask: The range of remote IPs can be communicated. For example, it is 255.255.255.0.
Proposal: There are two methods to check the authentication information, AH (authentication header)
and ESP (Encapsulating Security Payload).
ESP: Data will be encrypted and/or authentic. DES and 3DES encryption methods are supported. The
DES uses 56 bits as an encryption method. The 3DES uses 128 bits as an encryption method. MD5 and
SHA1 authentication protocols are supported. The authentication keys are a string and must be exactly
16 characters long for MD5 and 20 characters long for SHA1. The ESP can be one of following
proposals:
.ESP: DES without Authentication
.ESP: 3DES without Authentication
.ESP: DES with MD5
.ESP: DES with SHA-1
.ESP: 3DES with MD5
ESP: 3DES with SHA-1
.ESP: MD5 without Encryption
.ESP: SHA-1 without Encryption
AH: Data will be authentic only. MD5 and SHA1 authentication protocols are supported. The
authentication keys are a string and must be exactly 16 characters long for MD5 and 20 characters long
for SHA1.
PreShared Key: IKE authentication method. This is a string from 8 characters to 128 characters. Both
sides should use the same key.
Advanced IKE Setup: Press “Advanced IKE Setup” button, you will see Advanced IKE Setup page as
below figure. Then, you can configure the parameters of IKE.
