FIELD
DESCRIPTION
Phase 1
Negotiation
Mode
Press [SPACE BAR] to choose from
Main
or
Aggressive
and then press [ENTER].
See earlier for a discussion of these modes. Multiple SAs connecting through a
secure gateway must have the same negotiation mode.
Pre-Shared Key Prestige gateways authenticate an IKE VPN session by matching pre-shared keys.
Pre-shared keys are best for small networks with fewer than ten nodes. Enter your
pre-shared key here. Enter up to 31 characters. Any character may be used, including
spaces, but trailing spaces are truncated.
Both ends of the VPN tunnel must use the same pre-shared key. You will receive a
“PYLD_MALFORMED” (payload malformed) packet if the same pre-shared key is not
used on both ends.
Encryption
Algorithm
The Prestige and the remote IPSec router generate an encryption key from the Diffie-
Hellman key exchange. Prestige
DES
encryption algorithm uses a 56-bit key.
Triple DES (
3DES
), is a variation on DES that uses a 168-bit key. As a result,
3DES
is
more secure than
DES
. It also requires more processing power, resulting in slightly
increased latency and decreased throughput.
This implementation of
AES
uses a 128-bit key.
AES
is faster than
3DES
.
Press [SPACE BAR] to choose from
DES
,
3DES
or
AES
and then press [ENTER].
Authentication
Algorithm
MD5
(Message Digest 5) and
SHA1
(Secure Hash Algorithm) are hash algorithms
used to authenticate packet data. The
SHA1
algorithm is generally considered
stronger than
MD5
, but is slightly slower.
Press [SPACE BAR] to choose from
SHA1
or
MD5
and then press [ENTER].
SA Life Time
(Seconds)
Define the length of time before an IKE Security Association automatically
renegotiates in this
field. It
may range from 60 to 3,000,000 seconds (almost 35 days).
A short
SA Life Time
increases security by forcing the two VPN gateways to update
the encryption and authentication keys. However, every time the VPN tunnel
renegotiates, all users accessing remote resources are temporarily disconnected.
