VPN connect<strong>io</strong>ns<br />

Funct<strong>io</strong>n Here you can define the properties of the VPN connect<strong>io</strong>n according to your<br />

requirements and what you have agreed with the system administrator of the<br />

remote stat<strong>io</strong>n.<br />

ISAKMP-SA encrypt<strong>io</strong>n<br />

IPsec-SA encrypt<strong>io</strong>n<br />

ISAKMP-SA hash<br />

IPsec-SA hash<br />

Agree with the administrator of the remote stat<strong>io</strong>n which encrypt<strong>io</strong>n method<br />

will be used for the ISAKMP-SA and the IPsec-SA. The TAINY xMOD-V3-IO<br />

supports the following methods:<br />

� 3DES-192<br />

� AES-128<br />

� AES-192<br />

� AES-256<br />

AES-128 is the most frequently used method, and is therefore set as the<br />

default.<br />

The method can be defined differently for ISAKMP-SA and IPsec-SA.<br />

Note:<br />

The more bits in the encrypt<strong>io</strong>n algorithm - indicated by the appended<br />

number - the more secure it is. The method AES-256 is therefore considered<br />

the most secure. However, the longer the key, the more time the encrypt<strong>io</strong>n<br />

process takes and the more computing power is required.<br />

Agree with the administrator of the remote stat<strong>io</strong>n which method will be used<br />

for computing checksums/hashes during the ISAKMP phase and the IPsec<br />

phase. The following select<strong>io</strong>ns are available:<br />

� MD5 or SHA-1 (automatic detect<strong>io</strong>n)<br />

� MD5<br />

� SHA-1<br />

The method can be defined differently for ISAKMP-SA and IPsec-SA.<br />

ISAKMP-SA mode Agree with the administrator of the remote stat<strong>io</strong>n which method will be used<br />

for negotiating the ISAKMP-SA. The following select<strong>io</strong>ns are available:<br />

� Main mode<br />

� Aggressive mode<br />

DH/PFS group Agree with the administrator of the remote stat<strong>io</strong>n the DH group for the key<br />

exchange.<br />
