Ada beberapa metode (dan perintah) yang digunakan untuk mengkonfigurasi NAT. Tiga metode tersebut di antaranya Static NAT , Dynamic NAT, dan satu lagi TCP Load Balancing.
Static NAT Configuration
router#configure terminal router(config)#ip nat inside source static local-ip global-ip [overload] router(config)#interface interface-id router(config-if)#ip nat inside router(config-if)#interface interface-id router(config-if)#ip nat outside router(config-if)#end
Simpan pengaturan pada NVRAM
router#copy run start
Untuk melihat tabel NAT bisa menggunakan perintah berikut :
router#show ip nat translation
Dynamic NAT Configuration
router#configure terminal
router(config)#ip nat pool pool-name start-ip end-ip {netmask netmask | prefix-length prefix-length}
router(config)#access-list -number permit source [source-wildcard]
router(config)#ip nat inside source list access-list-number pool pool-name [overload]
router(config)#interface interface-id
router(config-if)#ip nat inside
router(config-if)#interface interface-id
router(config-if)#ip nat outside
router(config-if)#end
Simpan pengaturan pada NVRAM
router#copy run start
Untuk melihat tabel NAT bisa menggunakan perintah berikut :
router#show ip nat translation
TCP Load Balancing Configuration
router#configure terminal
router(config)#ip nat pool pool-name start-ip end-ip {netmask netmask | prefix-length prefix-length} type rotary
router(config)#access-list access-list-number permit source [source-wildcard]
router(config)#ip nat inside destination-list access-list-number pool pool-name
router(config)#interface interface-id
router(config-if)#ip nat inside
router(config-if)#interface interface-id
router(config-if)#ip nat outside
router(config-if)#end
Simpan pengaturan pada NVRAM
router#copy run start
