AES (Advanced Encryption Standard)
The Advanced Encryption Standard (AES) is a symmetric key encryption
technique, usually using a 128-bit, 192-bit and 256-bit key. AES is a
commonly seen and adopted nowadays.
NULL Algorithm
The NULL Algorithm is an instant and convenient alternative for connection.
It is merely a simple replacement for ESP (Encapsulating Security Payload)
without any cryptograph protection.
SHA1 (Secure Hash Algorithm-1)
The SHA1 is a revision of SHA (Secure Hash Algorithm). It has improved
the shortcomings of SHA. By producing summary hash values, it can
achieve an algorithm up to 160 bits.
MD5 Algorithm
MD5 (Message Digest Algorithm 5) processes a variable-length message
into a fixed–length output of 128 bits.
GRE / IPSec
The GRE (Generic Routing Encapsulation) comes in packet packing
function without any encryption against monitoring and attacking. Normally,
the GRE needs to cooperate with IPSec so as to provide a secure
connection.
Extended Authentication (XAuth)
XAuth provides an additional level of authentication. It uses a Request/
Reply mechanism to provide the extended authentication. XAuth is also
referred to as two factor authentication.
The Account Name under Extended Authentication (XAuth) are the accounts
listed under Policy > Authentication > Account.
Terms in One-Step IPSec
One-Step IPSec
IPSec VPN can be established within just one step as follows:
Go to Policy Object > VPN > One-Step IPSec and then refer to the
following:
Specify a name for the IPSec rule.
Select a WAN port for Interface.
Tick the radio box of "LAN 1" (leave the drop-down list as default).
Specify the Remote Gateway (Static IP or Hostname).
Specify the Remote IP Address / Netmask.
Type a string as the pre-shared key.
Click OK to complete the settings.
