Enable port forwarding in TM Innacomm W3400V

Recently it was so hard for me to download a movie, 10kbps average...Some say streamyx is blocking p2p app....Arrrghhh...freaking me...
Then I starts searching for solution and yet.....PORT FORWARDING....hehe~
But how can I enable port forwarding in the TM noob router ??? Here is it....

Steps:

1. Login your router. (In the browser address bar, type 192.168.1.1)
2. User name and password ( I believe default would be tmadmin / tmadmin)
3. Go to "Advance Setup" ===> "NAT" ===> "Virtual Servers"
4. Then, "Add". After that you will see screen as below:  
5. Choose "Custom servers" put whatever name you like.
6. Put your ip address (command prompt --> ipconfig, will get your ip address) at the "Server IP Address"
7. Put the port number you would like to forwarded to in the port columns. (Not very sure about the difference between External and Internal port, I put the same)
8. "Save / Apply" , your are done !!!

Now, yeah....get back my superb speedsssss.....

*** FYI, I am using Thunder 7 and I manually change the setting to the port I setup in the router.
