[FW-1] NAT Problem

[Biniam Sahlezghi]

My firewall is running in NT machine   My machine has two NIC cards one with real Ip address which has a direct gateway and the other with fake IP. Now here I want to use NAT for the fake IP with the hide option of the real IP in the Network Object properties and the rule is created authomathically. Now my fake IP from the workstation computers can not go outside browsing the  internet. In the TCP/IP propperties of the NT I have selected  enable IP Routing. What do you think the problem and the solution
