Field
Description
•
Preshared Keys
(default value): If you do not use certific-
ates for the authentication, you can select Preshared Keys.
These are configured during peer configuration in the IPSec
Peers menu. The preshared key is the shared password.
•
DSA Signature
: Phase 1 key calculations are authenticated
using the DSA algorithm.
•
RSA Signature
: Phase 1 key calculations are authenticated
using the RSA algorithm.
•
RSA Encryption
: In RSA encryption the ID payload is also
encrypted for additional security.

This field enables you to select one of your own certificates for
authentication. It shows the index number of this certificate and
the name under which it is saved. This field is only shown for
authentication settings based on certificates and indicates that a
certificate is essential.
Mode
Select the phase 1 mode.
Possible values:
•
Aggressive
(default value): The Aggressive Mode is neces-
sary if one of the peers does not have a static IP address and
preshared keys are used for authentication; it requires only
three messages for configuring a secure channel.
•
Main Mode (ID Protect)
: This mode (also designated
Main Mode) requires six messages for a Diffie-Hellman key
calculation and thus for configuring a secure channel, over
which the IPSec SAs can be negotiated. A condition is that
both peers have static IP addresses if preshared keys are
used for authentication.
Also define whether the selected mode is used exclusively
(Strict), or the peer can also propose another mode.
Local ID Type
Select the local ID type.

•
