connection attempts will be rejected.
•

- Only incoming connections will be accepted.
Outgoing traffic which would otherwise result in a connection

Authentication
•
RSA Signature
requires that both VPN endpoints have valid
Certificates issued by a CA (Certification Authority).
•
For
Pre-shared key
, enter the same key value in both endpoints.
The key should be at least 8 characters (maximum is 128 charac-
ters). Note that this key is used for the IKE SA only. The keys
used for the IPsec SA are automatically generated.
Encryption
Select the desired method, and ensure the remote VPN endpoint uses
the same method.
The "3DES" algorithm provides greater security
than "DES", but is slower.
IKE Exchange
Mode
Select the desired option, and ensure the remote VPN endpoint uses
the same mode. Main Mode provides identity protection for the hosts
initiating the IPSec session, but takes slightly longer to complete.
Aggressive Mode provides no identity protection, but is quicker.
