•
Secure Gateway
:
Any
displays in this field if it is not configurable for the chosen scenario. Otherwise,
enter the WAN IP address or domain name of the remote IPSec device (secure gateway) to identify
the remote IPSec device by its IP address or a domain name. Use 0.0.0.0 if the remote IPSec device
has a dynamic WAN IP address.
•
My Address (interface)
: Select an interface from the drop-down list box to use on your Zyxel Device.
•
Negotiation Mode
: This displays
Main
or
Aggressive
:
•
Main
encrypts the ZyWALL/USG’s and remote IPSec router’s identities but takes more time to
establish the IKE SA
•
Aggressive
is faster but does not encrypt the identities.
The ZyWALL/USG and the remote IPSec router must use the same negotiation mode. Multiple SAs
connecting through a secure gateway must have the same negotiation mode.
•
Encryption Algorithm
:
3DES
and
AES
use encryption. The longer the key, the higher the security (this
may affect throughput). Both sender and receiver must use the same secret key, which can be used
to encrypt and decrypt the message or to generate and verify a message authentication code. The
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
increased latency and decreased throughput.
AES128
uses a 128-bit key and is faster than 3DES.
AES192 uses a 192-bit key, and AES256 uses a 256-bit key.
•
Authentication Algorithm
:
MD5
gives minimal security and
SHA512
gives the highest security. MD5
(Message Digest 5) and SHA (Secure Hash Algorithm) are hash algorithms used to authenticate
packet data. The stronger the algorithm the slower it is.
•
Key Group
:
DH5
is more secure than
DH1
or
DH2
(although it may affect throughput). DH1 (default)
refers to Diffie-Hellman Group 1 a 768 bit random number. DH2 refers to Diffie-Hellman Group 2 a 1024
bit (1Kb) random number. DH5 refers to Diffie-Hellman Group 5 a 1536 bit random number.
•
SA Life Time
: Set how often the Zyxel Device renegotiates the IKE SA. A short SA life time increases
security, but renegotiation temporarily disconnects the VPN tunnel.
•
NAT Traversal
: Select this if the VPN tunnel must pass through NAT (there is a NAT router between the
IPSec devices).
