topologi diatas menggunakan ip publiknya ada di dalam,sedangkan ip privatenya ada di luar
kita jangan bingung,karena pada umumnya ip private yang di gunakan hnya sebagai penghubung saja.
Dengan melihat jaringan seperti yang di atas kita hubungkan dengan ip static menuju ip public dan dari ip public menuju provider kita menggunakan default routing,
Sedangakan untuk jaringan bagian dalam kita NAT kan ip public kita. Di sebelah dalam router kita gunakan OSPF untuk menyambungkan jaringan kita,OSPF ini hanya sampai pada router dimana ip public.
pertama kita konfigurasi R1
Router(config)#hostname R1
R1(config)#
R1(config)#interface FastEthernet0/0
R1(config-if)#
R1(config-if)#exit
R1(config)#interface FastEthernet0/1
R1(config-if)#ip address 222.222.222.222 255.255.255.0
R1(config-if)#no shutdown
%LINK-5-CHANGED: Interface FastEthernet0/1, changed state to up
%LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/1, changed state to up
R1(config-if)#
R1(config-if)#exit
R1(config)#interface FastEthernet0/0
R1(config-if)#
R1(config-if)#exit
R1(config)#interface FastEthernet0/0
R1(config-if)#ip address 192.168.1.1 255.255.255.0
R1(config-if)#ip address 192.168.1.1 255.255.255.252
R1(config-if)#no shutdown
%LINK-5-CHANGED: Interface FastEthernet0/0, changed state to up
Selanjutnya kita pasang ip static untuk menghubungkan ip public dengan ip provider
R1(config)#ip route 111.111.111.0 255.255.255.252 192.168.1.2
R1(config)#

R2(config-if)#n sh

%LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/1, changed state to up
R2(config-if)#ex
R2(config)#in

R2(config)#interface fastEthernet 0/0
R2(config-if)#ip add 111.111.111.2 255.255.255.224

%LINK-5-CHANGED: Interface FastEthernet0/0, changed state to up
%LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/0, changed state to up
R2(config-if)#ex
Selanjutnya kita konfigurasi default routing
R2(config)#ip route 0.0.0.0 0.0.0.0 192.168.1.1
R3(config)#interface fastEthernet 0/1
R3(config-if)#n shutdown
