How to Establish a TCP/IP Connection to a System Behind a Cayman 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 Cayman 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. Connect to your router setup home page
  2. Click on the Pinhole button.
  3. Click on the Export Mode button.

  4. Under the Name field, enter in Timbuktu Pro
  5. Select UDP from the pop-up menu
  6. In the External Port Start and External Port End field, enter 407.
  7. In the Internal IP Address field, type the internal IP of the host machine you wish to establish a Timbuktu Pro session to.
  8. Enter 407 in the Internal Port field.
  9. Click Add
  10. Repeat steps 4-9 to enter in TCP 1417,1418,1419 and 1420

    Note: Mac to Mac connections only requires TCP 407 open

  11. Now click on the Home button
  12. At the home page, restart your router to allow the changes to take effect
