I'm really stuck on this one and I have been told stack over flow is a great place to come for advice.
I have a machine running Windows 7 Professional with two internal gigabit NICs. I have enabled IP routing using the registry key "IPEnableRouter", setting it to 1.
This is the output of ipconfig:

I've set this up on a couple of machines before years ago and it worked fine, I guess I am just forgetting something, but it is driving me crazy now. From the 192.168.1 network I can ping 192.168.1.1 and 172.16.65.65, but not any of the other hosts on the 172.16 network. So all the hosts in the 192 network have no access.
I've even tried enabling the routing and remote access service, but that made no difference. I'm tried with all firewalls disabled as well to ensure it wasn't being blocked.
When I trace a ping from 192. to the internet it gets to 172.16.65.65 and then never moves on, it is like the machine just won't forward the packets on, but I do not know why.
Any advice or things to try would be very appreciated and if you need anymore information let me know.
