How to Configure Dynamic NAT on Cisco Router in GNS3 | What is Dynamic NAT | SYSNETTECH Solutions ► Article ► goo.gl/huZAVb Read More ⬇️ ✅ S U B S C R I B E ► goo.gl/8d0iG9 This video shows you how to configure Dynamic NAT on Cisco Router using the GNS3 network simulator program and VMware virtual machine. To enable Dynamic NAT on GNS3: Step 1: If you have not installed GNS3 on Windows, Linux, and MacOS before, please refer to the following videos. Windows ➦ www.youtube.com/watch?v=uhWt6TPNp-A Linux / Debian ➦ www.youtube.com/watch?v=_HsKS4iwr3M Linux / Linux Mint ➦ www.youtube.com/watch?v=XU6gf_Reiuk Linux / Ubuntu ➦ www.youtube.com/watch?v=8atzceBgN-c MacOS ➦ www.youtube.com/watch?v=MWStTRpwqBY Step 2: After you have done the GNS3 setup, open GNS3 and create a new project to configure #NAT. Step 3: Connect the two virtual machines that you created on VMware Workstation on GNS3 to the Cloud. If you do not know how to use virtual machines on GNS3, please refer to the following video or article. Video ➦ www.youtube.com/watch?v=SwE9VaZ7lXQ Article ➦ www.sysnettechsolutions.com/en/gns3/integrate-vmware-with-gns3/ Step 4: Add one #Cisco Router and Cisco Switch to the GNS3 workspace. Step 5: Connect the Cisco Switch to the Cisco #Router. Step 6: Run the virtual machines you have added and configure their IP address configurations. Step 7: Add one Cloud to GNS3 and then open its settings and select Ethernet from the Generic Ethernet NIO section and save the settings. Step 8: After preparing the network topology for NAT, test the network connection by pinging the FastEthernet0/0 interface of Cisco Router over the virtual machines. Step 9: Configure the IP address of Cisco Router's WAN interface with the ip address dhcp command. Step 10: The IP address on the Router's WAN interface on the GNS3 will be allocated over the ADSL Modem. Step 11: Now ping the WAN interface from the virtual machines and test the connection. Step 12: Ping the Google DNS server from the virtual machines and check the Internet connection. Step 13: Virtual machines will not be able to access the Internet without Dynamic NAT. Step 14: Run the following commands to enable Dynamic NAT. R1# conf t R1(config)# interface fastethernet0/0 R1(config-if)# ip address 192.168.8.1 255.255.255.0 R1(config-if)# ip nat inside R1(config-if)# no shutdown R1(config-if)# exit R1(config)# interface fastethernet0/1 R1(config-if)# ip address dhcp R1(config-if)# ip nat outside R1(config-if)# no shutdown R1(config-if)# exit R1(config)# access-list 1 permit 192.168.8.0 0.0.0.255 R1(config)# ip nat pool DYNAMICNAT 192.168.1.20 192.168.1.25 netmask 255.255.255.0 R1(config)# ip nat inside source list 1 pool DYNAMICNAT R1(config)# exit R1# copy running-config startup-config After configuring #DynamicNAT, VMware virtual machines will be able to access the Internet. Step 15: You can use the following show and debug commands to verify NAT. ➦ show ip nat translations ➦ clear ip nat translation * ➦ show ip nat statistics ➦ show log ➦ debug ip nat translations ➦ debug ip packet Step 16: Watch the video to understand Dynamic NAT.

It translates a group of real addresses to a pool of mapped addresses that are routable on the destination network. The mapped pool may include fewer addresses than the real group. When a host you want to translate accesses the destination network, the ASA assigns the host an IP address from the mapped pool. The translation is added only when the real host initiates the connection.
