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)#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-MLS(config-router)#exit

         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
