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.
