Hello Rene, Laz, forum members.
I rebuild this lab in GN3: c3620-a3jk8s-mz.122-26c.image
Again de outcome is different then what is shown in the lessons. I am sure that the configurations are right.
host 1 config.txt (898 Bytes)
host 2 config.txt (896 Bytes)
Ip nat translations outcome.txt (6.5 KB)
NAT config.txt (1.4 KB)
web1 config with and without IP routing.txt (1.7 KB)
What is the reason for the different outcome?
I played with an extra host pc 1 and changed the IP address a few times. You can see that NAT gives out new IP addresses every time I changed te IP address of PC1.
I enabled debug IP nat
on the NAT device.
When I give the command show ip nat tranlation
the outcome is different then the outcome in de lesson! I don’t see the Outside local of global ip addresses.
See configs and topology attached to this ticket.
Please can someone explain why I get a different outcome while the configurations are identical?
Best regards,
Michel

Same configuration. In CML it is working and the outcome is as expected.
