Policy Enforcement Point Configuration

EncrypTight Policy Enforcement Points (PEPs) can be configured for Layer 2 or Layer 3/4 operation. Models include:

●ET0010A

●ET0010A

●ET1000A

In most cases, when you install and configure the PEPs, you do not need to make addressing changes or other routing changes. The PEPs implement a network mode ESP transport mechanism that preserves all header information. The entire original packet is encrypted and a copy of the original header is used as the header for the new packet. This allows the PEPs to operate transparently, without requiring changes to your existing network addressing. You should maintain your existing network gateways as configured. You should not configure the local port on a PEP as a gateway address.

To prepare the PEPs for operation with EncrypTight:

●Perform basic installation tasks.

Perform initial setup as directed in the PEP’s Installation Guide. At a minimum, this consists of connecting cables to the PEP’s communication ports and setting the management port IP address.

When they are first installed, ETEP PEPs pass all traffic in the clear until they receive policies. Refer to the documentation for your PEPs for more information on initial behavior and how to make sure the PEPs are properly installed.

If you plan to use a PEP with EncrypTight distributed key policies, you should not configure any other types of policies on the PEP before you enable EncrypTight. Doing so can have undesirable effects.

●Configure the appliances in the EncrypTight software.

Using the ETEMS Appliance Manager feature in EncrypTight, add and configure each PEP. Refer to the sections below for configuration settings that are required for distributed key and negotiated key polices.

●For distributed key policies, see “Adding a New PEP in ETEMS” on page 148

●For point-to-point negotiated policies, see “Creating Layer 2 Point-to-Point Policies” on page 335
