Konfigurasi NAT di Cisco Packet

Konfigurasi NAT di Cisco Packet Tracer - hai bre pada postingan kali ini saya akan sedikit membahas tentang NAT di cisco packet tracer berikut adalah langkah langkahnya :


Topologi :

Konfigurasi ip address pada setiap router :

            Pada router IDN-R1 :

IDN-R1(config)#int fa0/0 IDN-R1(config-if)#ip address 100.100.100.250 255.255.255.0 IDN-R1(config-if)#no shutdown IDN-R1(config-if)#exit IDN-R1(config)#int se2/0 IDN-R1(config-if)#ip address 18.18.18.1 255.255.255.0 IDN-R1(config-if)#no shutdown IDN-R1(config-if)#exit

            Pada router IDN-R2 :

IDN-R2(config)#int fa0/0 IDN-R2(config-if)#ip address 19.19.19.2 255.255.255.0 IDN-R2(config-if)#no shutdown IDN-R2(config-if)#exit IDN-R2(config)#int se2/0 IDN-R2(config-if)#ip address 18.18.18.2 255.255.255.0 IDN-R2(config-if)#clockrate 64000 IDN-R2(config-if)#no shutdown IDN-R2(config-if)#exit

            Pada router IDN-MLS :

IDN-MLS(config)#int fa0/1 IDN- MLS(config-if)#no switchport IDN- MLS(config-if)#ip address 19.19.19.1 255.255.255.0 IDN- MLS(config-if)#no shutdown IDN- MLS(config-if)#exit IDN- MLS(config)#int fa0/2 IDN- MLS(config-if)#no switchport IDN- MLS(config-if)#ip address 16.16.16.1 255.255.255.0 IDN- MLS(config-if)#no shutdown IDN- MLS(config-if)#exit IDN- MLS(config)#int fa0/3 IDN- MLS(config-if)#no switchport IDN- MLS(config-if)#ip address 13.13.13.1 255.255.255.0 IDN- MLS(config-if)#no shutdown IDN- MLS(config-if)#exit IDN- MLS(config)#int vlan 10 IDN- MLS(config-if)#ip address 14.14.14.1 255.255.255.0 IDN- MLS(config-if)#exit IDN- MLS(config)#int vlan 20 IDN- MLS(config-if)#ip address 15.15.15.1 255.255.255.0 IDN- MLS(config-if)#exit IDN- MLS(config)#int vlan 30 IDN- MLS(config-if)#ip address 11.11.11.1 255.255.255.0 IDN- MLS(config-if)#exit

            Pada IDN-MLS :

IDN-MLS(config)#ip dhcp pool VLAN10 IDN-MLS(dhcp-config)#network 14.14.14.0 255.255.255.0 IDN-MLS(dhcp-config)#default-router 14.14.14.1 IDN-MLS(dhcp-config)#dns-server 16.16.16.250 IDN-MLS(dhcp-config)#exit IDN-MLS(config)#ip dhcp pool VLAN20 IDN-MLS(dhcp-config)#network 15.15.15.0 255.255.255.0 IDN-MLS(dhcp-config)#default-router 15.15.15.1 IDN-MLS(dhcp-config)#dns-server 16.16.16.250 IDN-MLS(dhcp-config)#exit IDN-MLS(config)#ip dhcp excluded-address 14.14.14.2 14.14.14.10 IDN-MLS(config)#ip dhcp excluded-address 15.15.15.2 15.15.15.10

Konfigurasi VLAN dan VTP 

            Pada switch IDN-MLS :

IDN-MLS(config)#vlan 10 IDN-MLS(config-vlan)#name C1 IDN-MLS(config-vlan)#exit IDN-MLS(config)#vlan 20 IDN-MLS(config-vlan)#name C2 IDN-MLS(config-vlan)#exit  IDN-MLS(config)#vlan 30 IDN-MLS(config-vlan)#name ADMINISTRATOR-IDN IDN-MLS(config-vlan)#exit IDN-MLS(config)#vtp mode server IDN-MLS(config)#vtp domain idn.com IDN-MLS(config)#vtp password 123 IDN-MLS(config)#int range fastEthernet 0/3 - fastEthernet 0/5 IDN-MLS(config-if-range)#switchport trunk encapsulation dot1q IDN-MLS(config-if-range)#switchport mode trunk

            Pada IDN-SW2 :

IDN- SW2(config)#vtp mode client IDN- SW2(config)#vtp domain idn.com IDN- SW (config)#vtp password 123 IDN-SW2(config)#int range fastEthernet 0/2 - fastEthernet 0/3 IDN-SW2(config-if-range)#switchport mode access IDN-SW2(config-if-range)#switchport access vlan 30

Pada IDN-SW3 :

IDN- SW3(config)#vtp mode client IDN- SW3(config)#vtp domain idn.com IDN- SW3(config)#vtp password 123 IDN-SW3(config)#int fastEthernet 0/2 IDN-SW3(config-if)#switchport mode access IDN-SW3(config-if)#switchport access vlan 10 IDN-SW3(config-if)#exit IDN-SW3(config)#int range fastEthernet 0/3 - fastEthernet 0/4 IDN-SW3(config-if-range)#switchport mode access IDN-SW3(config-if-range)#switchport access vlan 20 IDN-SW3(config-if-range)#exit

Pada IDN-SW4 :

IDN- SW4(config)#vtp mode client IDN- SW4(config)#vtp domain idn.com IDN- SW4(config)#vtp password 123 IDN-SW4(config)#int fastEthernet 0/2 IDN-SW4(config-if)#switchport mode access IDN-SW4(config-if)#switchport access vlan 10 IDN-SW4(config-if)#exit IDN-SW4(config)#int range fastEthernet 0/3 - fastEthernet 0/4 IDN-SW4(config-if-range)#switchport mode access IDN-SW4(config-if-range)#switchport access vlan 20 IDN-SW4(config-if-range)#exit

Konfigurasi EIGRP :

         Pada IDN-MLS :

         Pada IDN-R2 :

IDN-R2(config)#router eigrp 100 IDN- R2(config-router)#no auto-summary IDN- R2(config-router)#network 19.19.19.0 0.0.0.255 IDN- R2(config-router)#exit

Konfigurasi NAT :

            Pada IDN-R2 :

IDN-R2(config)#ip nat pool NAT 18.18.18.50 18.18.18.100 netmask 255.255.255.0 IDN-R2(config)#ip nat inside source list 1 pool NAT overload IDN-R2(config)# access-list 1 permit any IDN-R2(config)#int fastEthernet 0/0 IDN-R2(config-if)#ip nat inside IDN-R2(config-if)#exit IDN-R2(config)#int serial 2/0 IDN-R2(config-if)#ip nat outside IDN-R2(config-if)#exit IDN-R2(config)#ip route 0.0.0.0 0.0.0.0 18.18.18.1

            Pada IDN-R1 :

IDN-R1(config)#ip nat pool NAT-INT 18.18.18.50 18.18.18.100 netmask 255.255.255.0 IDN-R1(config)#ip nat inside source list 1 pool NAT-INT overload IDN-R1(config)# access-list 1 permit any IDN-R1(config)#int serial 2/0 IDN-R1(config-if)#ip nat outside IDN-R1(config-if)#exit IDN-R1(config)#ip route 0.0.0.0 0.0.0.0 18.18.18.1

            Pada IDN-MLS :

IDN-MLS(config)#ip route 0.0.0.0 0.0.0.0 19.19.19.2
