NAT Port Forwarding


Your network at home has been configured for NAT so you and the rest of your family can access the Internet. You also have a webserver and a SSH server at home and you would like those to be accessible to the rest of the world. Time for some good old port forwarding on your Cisco router.


  • All IPv4 addresses have been preconfigured for you.
  • Static routes have been configured on the webservers and the host for full connectivity.
  • When router Host sends an IP packet to IP address port 80 it should be sent to the webserver.
  • When router Host sends an IP packet to IP address port 22 it should be sent to the SSH server.

It took me 1000s of hours reading books and doing labs, making mistakes over and over again until I mastered all the protocols for CCNA.
