IPSec requires the Security software (RTUSEC)

and a Feature Key on all products.

This section explains how you can configure IPSec tunnels, by setting up the menus
below the

IP > IPSec menu

, for an IPSec tunnel with pre-shared keys or an IPSec tunnel

with IKE.

5.10.1 Protocols and algorithms

Security associations (both tunnelled and transport) may be configured with a range of
protocols/combination of protocols:

AH – authentication header only

ESP – encapsulating security protocol only

ESP-AH – combination of ESP & AH protocols

ESP-AUTH – encapsulating security protocol with authentication

Any of the following encryption algorithms:

3DES

AES128

AES192

AES256

Any of the following hash algorithms:

SHA1

MD5

AES128

SHA2-256

SHA2-384

SHA2-512

If any of the permissible protocols are unsuitable for your applications, you are able to
allow/disallow the use of certain protocols using the

‡IP > IPSec > IKE Crypto

Algorithms menu

‡IP > IPSec > IKE Hash Algorithms menu

‡IP > IPSec

> IKE DH Groups menu

and

‡IP > IPSec > IKE Auth Algorithms menu

5.10.2 IPSec tunnels

Secure VPNs can be created between two Vocality units or a Vocality device and
another IPSec device through the use of IPSec tunnels. Alternatively it is possible to use
IP aggregates secured using IPSec transport encryption.
