VPN and Multi-Domain Security Management

This section covers the configuration of Global VPN communities.

Global VPN Communities

Large enterprises often have branches in different cities or countries. With each branch managed by a different Domain, the enterprise can use a central management system to centrally manage all the various Domains. When connectivity is established, the connections must be secure and have high levels of privacy, authentication, and integrity.

A Global VPN Community connects the enterprise's gateways through VPN and lets the enterprise manage them under one network. You define the Global VPN Community in the Global Domain. The Multi-Domain Server utilizes its knowledge about the different Domain Management Server environments to create a VPN community which can manage them.

VPN Connectivity

When you establish a Global VPN Community, it replaces part of the configuration of Externally Managed Security Gateways and automates the exchange of certificates for each Domain Management Server.

These trusted entities create VPN trust in a Multi-Domain Security Management deployment:

The ICA of the Domain Management Server issues certificates used by Domain Security Gateways to create SIC trust. Each Security Gateway supports certificates issued by the CAs of the other Domains.

For more information on VPN with Externally Managed Gateways, see the R80.20 Site to Site VPN Administration Guide.

Configuring Global VPN Communities

Workflow for Creating a Global VPN Community

To create a Global VPN Community:

  1. Configure a VPN Domain on each participating Security Gateway.
  2. Enable each participating Security Gateway for global use.
  3. In the Global Domain, define a VPN Community, and add the Global Security Gateway objects to the Global VPN Community. The Global Security Gateway objects represent the participating Domain Security Gateways.
  4. Define a Security Policy - You can create a Global policy and assign it to the Local Domains, or you can create the Security Policy rules only in the Local Domains.
  5. Assign the Global configuration to the applicable Domains. After assignment, you must also install the policy on the participating Security Gateways.

Step 1 - Configuring a VPN Domain on Each Security Gateway

You define the Domain Security Gateways in the Domain SmartConsole.

To define a VPN Domain on a Security Gateway:

In the gateway editor:

  1. In General Properties, enable IPSec VPN.
  2. In Network Management > VPN Domain, configure the settings for the VPN Domain. you must define a VPN Domain and specify if the VPN Domain is based on the network topology or a specific IP address range.

For information on configuration of a VPN Domain , see the R80.20 Site to Site VPN Administration Guide.

Multi-Domain Server holds these IP address ranges used by the Security Gateways. During the assignment of the Global configuration, the Multi-Domain Server transfers this information to all the Domains with participating gateways in the Global VPN Community.

Step 2 - Enabling Gateways for Global Use

Repeat this step for all Security Gateways that are to participate in the Global VPN Community:

In the Multi-Domain Server SmartConsole > Gateways & Servers view, right-click a Security Gateway and select Enable Global Use.

A global Security Gateway object and a VPN Domain object are created for the Security Gateway in the Global Domain. Different Domains can coincidentally contain Security Gateways with the same name. Because each global Security Gateway object must have its own unique Global Name, the Global Names Template automatically assigns a unique name for each global Security Gateway. The default global name format is: <Security Gateway Name>_of_<Domain Name>.

For example:

Note - When the local Domain that manages the gateway to be used globally has the active server on the standby Multi-Domain Server, you cannot use the gateway globally.

Enabling clusters for global use

You can enable a cluster for global use in the same way that you enable a Security Gateway. A global cluster object and a VPN Domain object will be created for the cluster in the Global Domain.

Step 3 - Creating the VPN Global Community

After you enabled VPN on the gateways, and enabled the gateways for global use, you can create the Global VPN Community.

To create a Global VPN Community:

  1. In the Global Domain, go to Security Policies > Access Control > Access Tools > VPN Communities > New.
  2. Add the global Security Gateway objects, defined in step 1, as participating Security Gateways in the community.

To learn more about VPN communities, see the R80.20 Site to Site VPN Administration Guide.

Step 4 - Defining a Security Policy

The configuration of Security Gateways into a Global VPN Community does not automatically let the Security Gateways access each other. For the Security Gateways to communicate with each other you must define an Access Control Security Policy.

You can define the Access Control Security Policy in the Global Domain or in the Local Domains or both.

To define a Global Security Policy, see Global Policy Management. To learn more about the Access Control Security Policy Rule Base, see the R80.20 Security Management Administration Guide.

Step 5 - Assigning the Global Configuration to the Local Domains

After you create the Global VPN Community, and in some case, also the Global Policy, you must assign the Global configuration to the Local Domains. After assignment, install policy on the Local Domains.

To assign the global configuration to the Local Domains:

  1. Make sure you published all the changes made in the Global Domain.
  2. In the Multi-Domain Server SmartConsole > Multi-Domain view > Global Assignments, assign the Global objects to the Local Domains
  3. Install policy on the Security Gateways.

Note - All Security Gateways which participate in the Global VPN Community must use a Simplified VPN Policy.

For each Domain with Security Gateways in the Global VPN Community, a global CA Server object is created in the Global Domain. During the assignment process, the Multi-Domain Server automatically exports relevant Domain ICA information (such as the CA certificate) to all the Domain Management Servers with Security Gateways that participate in the community. This way, all the Security Gateways in the community can trust the others' ICAs.

After the assignment, the Global VPN Community object shows in each Domain with Security Gateways in the community. If you assign a Global Policy to a Domain that has no Security Gateways in the community, this Domain does not show the community object and the community Security Gateway objects.

Reassigning the Global Configuration to One or More Local Domains

If you make changes to the global configuration, reassign the configuration to the Domains.

To reassign the Global configuration to the Local Domains:

  1. In the Multi-Domain Server SmartConsole > Multi-Domain view > Global Assignments, select the Domains that have Security Gateways which participate in the Global VPN Community and click reassign.
  2. In the Reassign window, select Install policy on successful assignment. This installs the Global Policy on the Security Gateways which participate in the Global VPN Community.

    Note - This operation assigns the Policy to all selected Domains, and then installs the Policy on all Domain Security Gateways, in one step. It does not let you select specific Security Gateways on which to install the Policy. The selected Policy is installed on all Security Gateways in the selected Domains. Assigning the Policy to many Domains and all their Security Gateways can take some time. Use this option with caution.
