Which of the following would be a good starting point for troubleshooting if your router is not translating?

The show ip nat statistics command displays a summary of the NAT configuration as well as counts of active translation types, hits to an existing mapping, misses (causing an attempt to create a mapping), and expired translations.

The command ip nat pool <name> creates the pool that hosts can use to get onto the global Internet. What makes option B correct is that the range 171.16.10.65 through 171.16.10.94 includes 30 hosts, but the mask has to match 30 hosts as well, and that mask is 255.255.255.224. Option C is wrong because the pool name has a lower case "T" in the pool name. Pool name's are case sensitive.

NAT is not perfect and can cause some issues in some networks, but most networks work just fine. NAT can cause delays and troubleshooting problems, and some applications just won't work.

The command show ip nat translations will show you the translation table containing all the active NAT entries.

The host on the private network after translation is considered to be an inside global host.

The command clear ip nat translations * will clear all the active NAT entries in your translation table.

As in access-lists, you must configure your interfaces before NAT will provide any translations. On the inside networks you would use the command ip nat inside. On the outside interface, you will use the command ip nat outside.

You can configure NAT three ways on a Cisco router: static, dynamic, and NAT Overload (PAT).

Instead of the netmask command, you can use the prefix-length <length> statement.

The host on the global network after translation is considered to be an outside global host.
