cisco 800 port forwarding

  1. To enter Admin Mode ( will require root password )
    enable

    # To show currently configured Interfaces
    show ip interface

    # To show Current Port Forwards on Router
    show ip nat translations

    # To Enter Configuation Mode
    configure

    # To add Port Forwarding rules
    ip nat inside source static (TCPorUDP) (YourCompsIP) (PortToForward) interface (Ext.InterfaceName) (PortToForward)

    # Example: forward port 3389 TCP to the computer with ip 192.168.1.11
    ip nat inside source static tcp 192.168.1.11 3389 interface Dialer0 3389

    # End Configure Session
    Press CTRL-Z

    # Once you have entered the config, test it out and if it works,
    # issue this command to make it persistent:
    copy run start

    # When it says
    # Destination filename [startup-config]?
    # just press enter.
