Hi Ram,
thank you for your answer.
I don't think the solution will solved the problem. In your proposal it looks like the 150.50.5.69 is answering. I think 150.50.5.68 is answering but NAT-function will change the source address from 150.50.5.68 to 150.50.5.69 on the way back to R5. Another check can be done by doing a ping 150.50.5.70 By doing this the the solution seems not to work. What I'm looking for is to change the destination address when the packet is travelling from R5 to R8. By doing a 'ip nat inside destination ...' at R7 I thought I could change the destination address. I do not managed to do solve the problem by doing this.
Thank You
Erling Bjontegard
