Product(s): Microsoft Windows NT
Version(s): winnt:4.0
Operating System(s): 
Keyword(s): kb3rdparty

-------------------------------------------------------------------------------
The information in this article applies to:

- Microsoft Windows NT Server, Enterprise Edition version 4.0 
- Microsoft Windows NT Server version 4.0 
-------------------------------------------------------------------------------

SYMPTOMS
========

The Windows NT system does not forward packets, even though the Enable IP
Forwarding check box is selected in TCP/IP Properties.

CAUSE
=====

This problem may occur because Checkpoint Software's Firewall 1 software has
been installed and no routing security policy has been configured by the user
after installation.

RESOLUTION
==========

To resolve this problem, configure a security policy or disable the control of
IP forwarding by Firewall 1.

MORE INFORMATION
================

If no security policy has been configured, Firewall 1 assumes the most
restrictive policy, which is no forwarding of IP packets.
