How to establish a TCP/IP connection to a system behind a router

This brief guide is intended to help first time users of Timbuktu Pro quickly set up and establish a connection between two machines over TCP/IP through a NexLand router running Network Address Translation. This is by no means a definitive guide. There are alternate ways of establishing a Timbuktu Pro TCP/IP connection. This guide only presents one of them.

Following are the steps to take before the connection can be made.

1. Go to the Advanced Screen/level 2/User Defined
2. Enter the required data (See next section)
3. Click "Add"

Configuration Data

Name	Enter a descriptive name to identify this Server entry. ( eg. Timbuktu)
Enable	Use this to Enable or Disable support for this Server, as required.
IP Address	The IP Address of the PC on your LAN that is running the Server software.
Protocol	Select the protocol (TCP or UDP).
Internal Port Range	Enter the port number used by Timbuktu to connect the host machine. See below for port information
External Port Range	This will be the same as the Internal Port Number.

Connecting to the host machine

Once configured, anyone on the Internet can connect to your Timbuktu host machine. The IP address that Timbuktu guest machines would connect to your host machine with is the IP Address on the External MODEM Port field in either your STATUS SCREEN, ADVANCED SCREEN, or the Pre defined IP address in the PPPoE SCREEN.
