Table 68 AH and ESP
ESP AH
Encryption DES (default)
Data Encryption Standard (DES) is a
widely used method of data encryption
using a secret key. DES applies a 56-bit
key to each 64-bit block of data.
3DES
Triple DES (3DES) is a variant of DES,
which iterates three times with three
separate keys (3 x 56 = 168 bits),
effectively doubling the strength of DES.
AES
Advanced Encryption Standard is a
newer method of data encryption that
also uses a secret key. This
implementation of AES applies a 128-bit
key to 128-bit blocks of data. AES is
faster than 3DES.
Select NULL to set up a phase 2 tunnel
without encryption.
Authentication MD5 (default)
MD5 (Message Digest 5) produces a
128-bit digest to authenticate packet
data.
MD5 (default)
MD5 (Message Digest 5) produces a
128-bit digest to authenticate packet
data.
SHA1
SHA1 (Secure Hash Algorithm)
produces a 160-bit digest to
authenticate packet data.
SHA1
SHA1 (Secure Hash Algorithm)
produces a 160-bit digest to
authenticate packet data.
17.3 My IP Address
My IP Address is the WAN IP address of the Prestige. If this field is configured as 0.0.0.0,
then the Prestige will use the current Prestige WAN IP address (static or dynamic) to set up the
VPN tunnel. The Prestige has to rebuild the VPN tunnel if the My IP Address changes after
setup.
17.4 Secure Gateway Address
Secure Gateway Address is the WAN IP address or domain name of the remote IPSec router
(secure gateway).
If the remote secure gateway has a static WAN IP address, enter it in the Secure Gateway
Address field. You may alternatively enter the remote secure gateway’s domain name (if it
has one) in the Secure Gateway Address field.
