Para a manutenção e monitoração do NAT utilize os comandos:

1. show ip nat translations – mostra as traduções feitas pelo NAT;
2. show ip nat statistics – mostras as estatísticas do NAT.

Abaixo, um exemplo do comando “show ip nat translations” e “show ip nat statistics” do cenário da figura 1:

R_B#show ip nat translations
