 ===== Topologi =====
-Gambar topology

-Goals Topology
+**Tujuan** : Buat Jaringan LAN dapat untuk mengakses internet
+<hidden Proconfig>
+* **R1: Preconfig**
+<code js>
+hostname R1
+!
+ip dhcp excluded-address 192.168.1.1

 ===== Konfigurasi =====
-  * **Step 1 : Pembuatan VLANs**
-<code>
-Switch(config)#vlan 10
-Switch(config-vlan)#name BIRU
-Switch(config-vlan)#exit
-Switch(config)#vlan 20
+  * **R1 : Tentukan Interface inside dan outsite**
-Switch(config-vlan)#name MAGENTA
-Switch(config-vlan)#exit
+<code js>
+R1(config)#interface fastEthernet 0/0
+R1(config-if)#ip nat outside
+R1(config)#interface fastEthernet 0/1
+R1(config-if)#ip nat inside
 </code>
-  * **Step 2 : Assign VLANs ke Ports**
-<code>
-Switch(config)#interface f0/1
-Switch(config-if)#switchport mode access
-Switch(config-if)#switchport access vlan 10
-Switch(config-if)#exit
-Switch(config)#interface f0/2
+  * **R1 : Membuat ACL untuk range ip internal**
-Switch(config-if)#switchport mode access
-Switch(config-if)#switchport access vlan 10
+<code js>
-Switch(config-if)#exit
+R1(config)#access-list 1 permit 192.168.1.0 0.0.0.255
 </code>
+  * **R1 : Mempetakan ip pool yang telah dibuat ke ip private dgn dynamic nat**
+<code js>
+R1(config)#ip nat inside source list 1 interface  overload
+</code>
+  * **R1 : Apabila belum terseting automatis, Untuk memastikan dapat terhubung ke internet setinglah default gateaway**
+<code js>
+R1(config)#ip route 0.0.0.0 0.0.0.0 fastEthernet 0/0
