Note:
DH is a public-key cryptography scheme that allows two parties to establish a shared secret
over an insecure communications channel. It is also used within IKE to establish session keys.
2.
Select the
DH Group
. Options are:
•
Group 2
: Provides a 1024-bit Modular Exponential (MODP) keying strength.
•
Group 14
: Provides a 2048-bit MODP keying strength.
3.
Select one or more of the following
Hash - Encryption
algorithms:
•
SHA1 - Advanced Encryption Standard (AES)
•
SHA1 - Triple Data Encryption Standard (3DES)
•
MD5 - AES
•
MD5 - 3DES
Notes:
•
3DES is a variation on DES that uses a168-bit key. 3DES is more secure than DES.
•
AES is more secure than 3DES.
4.
Under
IKE Phase 2
, select the
IPsec Mode
.
Options are
Transport Mode
or
Tunnel Mode
.
Note:
Transport mode only encrypts the IP payload whereas Tunnel mode encrypts the IP header
and the IP payload. Tunnel mode provides protection for an entire IP packet by treating it as an
Authentication Header (AH), or Encapsulating Security Payload (ESP).
5.
If you select
Tunnel Mode
, under
Enable Security End Point Address
, select the address type.
Options are
Disabled
,
IPv4 Address
, or
IPv6 Address
.
6.
Under
IPsec Security
, select
ESP
,
AH
, or
BOTH
.
7.
Type the
Key Lifetime
, and select the units;
Seconds
,
Minutes
, or
Hours
.
8.
Under
Perfect Forward Secrecy (PFS)
, select
None
,
Group 2
, or
Group 14
.
Note:
PFS is disabled by default. PFS allows faster IPSec setup, but is not very secure.
9.
Under
Hash
, select from the following:
•
SHA1
•
MD5
•
None
10. If you selected
ESP
or
BOTH
for the
IPsec Security
type, select one or more of the following
Encryption
types:
Note:
Encryption
will not display if
IPsec Security
is set to
AH
.
•
AES
•
3DES
•
Null
