Identd Packet Filter Required for Some Applications w/ Proxy 2.0

 Last reviewed: November 19, 1997
Article ID: Q176946

The information in this article applies to:

  • Microsoft Proxy Server, version 2.0

SYMPTOMS

Some applications, such as File Transfer Protocol (FTP) or Internet Relay Chat (IRC) may pause for long periods of time or fail to connect when used from behind Microsoft Proxy Server 2.0 with packet filtering select (enabled).

CAUSE

The packet filtering feature of Proxy Server 2.0 may be blocking Identification Protocol (Identd) requests from the Internet. Some Internet servers try to use the Identd protocol to identify other hosts on the Internet.

RESOLUTION

The predefined filter for Identd needs to be added.

  1. Open the Winsock Proxy Service Properties, and select the Service tab.

  2. Under the Shared Services section, select Security. Choose Add, and select the Identd filter from the list of predefined filters.

    This will allow Identd traffic to pass through instead of being discarded by the proxy packet filter driver.

MORE INFORMATION

More information on the IdentD protocol can be found on the Internet in the RFC 1413.
