Hi,
I have 3 routers in GNS3. ONE TWO and THREE, placed in order.
TWO has NAT conf and yet I am unable to ping THREE (172.168.1.2) from ONE (10.0.0.1)

Thanks for your question blackninja.
I'm afraid I don't have any idea at all what [i]"I have 3 routers in GNS3. ONE TWO and THREE, placed in order."[/i] means.
It sounds to me like you are trying to connect two subnets that are very far apart in number. What are you running for a Subnet Mask??
