==Troubleshooting Checklists==<br />
<br />
* Translation Not Installed in the Translation Table<br />
* Correct Translation Entry Isn't Being Used<br />
* NAT Operating Correctly, But There Are still Connectivity Problems<br />
* NAT Translation for Port 80 Does not Work<br />
* %NAT: System busy. Try later<br />
* Large Translation Table Increases the CPU<br />
* % Public ip-address already mapped (Internal ip-address -> Public ip-address)<br />
* No Entries in the ARP table<br />
* Conclusion<br />
* Bad token 0, wanted TOK_NUMBER|TOK_PUNCT <br />

==How to Rule Out NAT==<br />
<br />
When you attempt to determine the cause of an IP connectivity problem, it helps to rule out NAT. Follow these steps to verify that NAT is operating as expected:<br />
<br />
* Based on the configuration, clearly define what NAT is supposed to achieve. At this point you may determine that there is a problem with the configuration.<br />
* Verify that correct translations exist in the translation table.<br />
* Use the show and debug commands to verify that the translation is occurring.<br />
* Review in detail what is happening to the packet and verify that routers have the correct routing information to move the packet along.<br />
<br />

==Sample Problem: Can Ping One Router But Not Another==<br />
<br />
show ip nat translation<br />
clear ip nat statistics<br />
show ip nat statistics<br />
ping 172.16.11.7<br />
show ip nat statistics<br />
show ip route<br />
<br />
