Packet Filter Driver Blocks All Non-proxy RequestsLast reviewed: December 17, 1997Article ID: Q174785 |
The information in this article applies to:
SYMPTOMSThe packet filter driver in Proxy Server version 2.0 blocks all non-proxy requests to and from the Proxy Server.
CAUSEThis only occurs when packet filtering is selected (enabled). The packet filter driver will not block applications that use any of the proxy services. Instead, the dynamic packet filter feature will automatically open the requested ports for these applications.
RESOLUTIONIf you run applications that access the Internet on the same computer that is running Proxy Server, you need to configure static filters. To add a custom or pre-defined static filter:
Common Packet FiltersFTP Server IN (Filter 1 of 2) Protocol = TCP Direction = IN Local Port = 21 Remote Port = Any FTP Server OUT (Filter 2 of 2) Protocol = TCP Direction = OUT Local Port = 20 Remote Port = Any HTTP Server (Port 8080) (Note, there is a pre-defined filter for port 80) Protocol = TCP Direction = IN Local Port = 8080 Remote Port = Any
MORE INFORMATIONFor additional information on packet filters, please see the "Setting Security Parameters" chapter in the Microsoft Proxy Server version 2.0 documentation. This article will be updated periodically with new packet filter examples.
