SYMPTOMS

Reverse proxying does not work with a single network card.

WORKAROUND

Using Proxy's Web Publishing feature to publish from the local web server works with a single network adapter.

Using Web Proxy's Web Publishing feature to publish from an internal Web server (reverse proxy) works with a single network adapter if two IP addresses are bound to that adapter. The IP addresses must be on different IP subnets and only one of the IP address can reside in the Proxy's Local Address Table (LAT).

STATUS

This behavior is by design.

MORE INFORMATION

Reverse proxying is a feature of Microsoft Proxy Server that enables clients to send requests to a Web publishing server connected behind the Proxy Server computer. You can place your Web server behind the Proxy Server computer to publish to the World Wide Web without compromising the security of the Web server or its data. Proxy Server "impersonates" a Web server to the outside world, while your Web server maintains access to internal network services.

You can run Microsoft Proxy Server on a computer with only a single internal network adapter, such as for a chained-downstream configuration or a caching-only configuration. In this configuration, some functionality such as packet filtering and reverse proxying will be lost.
