konfigurasi static nat dan dynamic nat

STATIC NAT

Pertama kita buat topologinya dulu:

jika sudah membuat topologi,selanjutnya kita masukan ip ke server dan pc secara static seperti gambar dibawah:

*perintah dibawah dikonfigurasi dirouter 0

Router>en

Router#conf t

Enter configuration commands, one per line. End with CNTL/Z.

Router(config)#int fa0/0

Router(config-if)#ip add 8.8.8.1 255.255.255.0

Router(config-if)#no sh

Router(config-if)#do wr

*perintah dibawah dikonfigurasi dirouter 0

Router>en

Router#conf t

Enter configuration commands, one per line. End with CNTL/Z.

Router(config)#int fa0/1

Router(config-if)#ip add 20.20.20.1 255.255.255.0

Router(config-if)#no sh

Router(config-if)#do wr

*perintah dibawah dikonfigurasi dirouter 1

Router>en

Router#conf t

Router(config)#int fa0/0

Router(config-if)#ip add 20.20.20.2 255.255.255.0

Router(config-if)#no sh

*perintah dibawah dikonfigurasi dirouter 1

Router>en

Router#conf t

Router(config)#int fa0/1

Router(config-if)#ip add 192.168.10.1 255.255.255.0

Router(config-if)#no sh

*perintah dibawah untuk mengaktifkan NAT STATIC nya;

Router>en

Router#conf t

Enter configuration commands, one per line. End with CNTL/Z.

Router(config)#ip nat inside source static 192.168.10.5 20.20.20.50

Router(config)#int fa0/1

Router(config-if)#ip nat outside

Router(config-if)#exit

Router(config)#int fa0/0

Router(config-if)#ip nat inside

Router(config-if)#exit

*perintah dibawah untuk membuat routing static:

router 0

ip route 0.0.0.0 0.0.0.0 20.20.20.2

router 1

ip route 0.0.0.0 0.0.0.0 20.20.20.1

DYNAMIC NAT

Keterangan : 

Router1 : Gig0/0 200.200.10.1/30
                Gig0/1 10.10.10.1/24

Router2 : Gig0/0 192.168.10.1/24
                Gig0/1 10.10.10.2/24

Server   : 200.200.10.2/30
PC0       : 192.168.10.2/24
PC1       : 192.168.10.3/24

Konfigurasi pada Router1 :

Router1>enable

Router1#conf ter
Router1(config)#int
Router1(config)#interface gi
Router1(config)#interface gigabitEthernet 0/0
Router1(config-if)#ip ad
Router1(config-if)#ip address 200.200.10.1 255.255.255.252
Router1(config-if)#no sh

Router1>enable
Router1#conf ter
Router1(config)#int
Router1(config)#interface gi
Router1(config)#interface gigabitEthernet 0/1
Router1(config-if)#ip ad

Router1(config-if)#ip address 10.10.10.1 255.255.255.0
Router1(config-if)#no sh

Router1(config-if)#exit

Router(config)#ip route 0.0.0.0 0.0.0.0 10.10.10.2
Router(config)#

Konfigurasi pada Router2 :

Router2>enable
Router2#conf ter
Enter configuration commands, one per line.  End with CNTL/Z.
Router2(config)#int
Router2(config)#interface gi
Router2(config)#interface gigabitEthernet 0/0
Router2(config-if)#ip ad
Router2(config-if)#ip address 192.168.10.1 255.255.255.0
Router2(config-if)#no sh

Router2>enable
Router2#conf ter
Enter configuration commands, one per line.  End with CNTL/Z.
Router2(config)#int
Router2(config)#interface gi
Router2(config)#interface gigabitEthernet 0/1
Router2(config-if)#ip ad

Router2(config-if)#ip address 10.10.10.2 255.255.255.0
Router2(config-if)#no sh

Router2(config-if)#exit

Router2(config)#ip route 0.0.0.0 0.0.0.0 10.10.10.1

Router2(config)#

Konfigurasi NAT Dynamic :

Router2(config)#int
Router2(config)#interface gi 0/0 
Router2(config-if)#ip na
Router2(config-if)#ip nat ins
Router2(config-if)#ip nat inside 

Router2(config-if)#exit
Router2(config)#interface gig 0/1
Router2(config-if)#ip na
Router2(config-if)#ip nat outs
Router2(config-if)#ip nat outside 
Router2(config-if)#ex
Router2(config)#ac
Router2(config)#access-list 1 per
Router2(config)#access-list 1 permit 192.168.10.0 0.0.0.255
Router2(config)#ip na
Router2(config)#ip nat poo
Router2(config)#ip nat pool poolR2 10.10.10.10 10.10.10.50 net
Router2(config)#ip nat pool poolR2 10.10.10.10 10.10.10.50 netmask 255.255.255.0 
Router2(config)#ip na
Router2(config)#ip nat ins
Router2(config)#ip nat inside sour
Router2(config)#ip nat inside source lis
Router2(config)#ip nat inside source list 1 pool poolR2
Router2(config)#
