The method you are using to port forward looks correct, but you would want to forward that to the IP address of the Hamachi server, not your personal computer. That is assuming of course that the hamachi server shows up in the devices connected to your router (I am not too familiar with hamachi). To check the port forwarding remember to have the server running as well, other wise it will say the port isn't forwarded correctly, when in truth it is.
So ya, looks like the port forwarding should be set up correctly, just make sure to use the internal IP of whatever device you have it running on (Hamachi in your case), and make sure the Tekkit server is running when you test the port forward. Finally if it doesn't work on hamachi try just running it on your computer normally and see if that works, you might need to do another port forward on your personal computer to the hamachi server you are running.
