Configuration via Local Pages

Page layout with Clicking Specify Additional Networks allows you to designate up to four addresses/ additional Networks subnets in case the Local Trusted Network can not be described by a single address/

subnet.

IKE Security Descriptor The IKE Security Descriptor bundles the security parameters used for the IKE Security Association (Phase1).

A number of IKE Security Descriptors are pre-configured in the SpeedTouch™, and can be selected from a list. Select a Security Descriptor in function of your security requirements. The remote VPN clients must comply with the IKE security parameters configured in the VPN server.

For example, the pre-configured IKE Security Descriptor AES_MD5, used in various examples throughout this document, contains the following settings:

Parameter

Value for AES_MD5

 

 

Cryptographic function

AES

 

 

Hash function

HMAC-MD5

 

 

Diffie-Hellman group

MODP768 (= group 1)

 

 

IKE SA lifetime in seconds.

3600 seconds (= 1 hour)

 

 

The contents of the IKE Security Descriptors can be verified via

Advanced > Peers > Security Descriptors.

It is recommended to use AES as preferred encryption method. AES is more advanced, compared to DES or 3DES. It is faster for comparable key lengths, and provides better security.

The IKE Security Descriptor bundles the security parameters used for the IKE

Security Association (Phase1).
