Routing Problems After Installing Checkpoint Firewall 1

ID: Q200775

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.
