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:
z Specify a name for the IPSec rule.
z Select a WAN port for Interface.
z Tick the radio box of “LAN 1” (leave the drop-down list as default).
z Specify
the Remote Gateway (Static IP or Hostname).
z Specify the Remote IP Address / Netmask.
z Type a string as the pre-shared key.
z Click
OK to complete the settings.
