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)
Following is the config on TWO.

Thanks for your question blackninja.
I'm afraid I don't have any idea at all what I have 3 routers in GNS3. ONE TWO and THREE, placed in order." 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??
