Here are some NAT troubleshooting tips:
- show ip nat translations
- show running-config
- show ip nat statistatics
- debug ip nat
- clear ip nat translations *
- Check inside and outside are placed on the correct interfaces
- Ensure the natpool covers the correct range of IPs
- Check the name of the pools are matched – I made a typo during testing and as a result NAT didn’t work
- Ensure the access-list is configured correctly to allow translation
