    I am having a problem with my inbound NAT translation/Port-forwarding. I am using NAT port-forwarding to allow traffic from the Internet to reach 18 servers. The problem is that this is working for a few of the servers and not for the rest, even though the configuration is identical for all of them. I have searched hi & low trying to find a solution and/or suggestions on how to troubleshoot this problem. I have read the cisco docs but have not found a usable answer in them either. Any assistance/suggestions would be greatly appreciated. I have include a copy of the NAT stats for you to look at. Thanks, Greg
