Virtual Multi-Homing

Virtual multi-homing allows you to use DNS names from different domains (for example test.com and sales.com). Each of these domain names must resolve to Access Gateway host.

Figure 2-18 Using Multiple DNS Names

Virtual multi-homing cannot be used with SSL. You must use this configuration with resources that need to be protected, but the information exchanged must be public information that does not need to be secure. For example, you could use this configuration to protect your web servers that contain the catalog of your shipping products. It isn’t until the user selects to order a product that you need to switch the user to a secure site.

Whether a client can use one DNS name or multiple DNS names to access Access Gateway depends upon the configuration of your DNS server. After you have configured your DNS server to allow multiple names to resolve to the same IP address, you are ready to configure Access Gateway.

To create a virtual multi-homing proxy service, see Creating a Second Proxy Service, and select Virtual for the multi-homing type.
