Problem with ports

[Huntsman]

Hey guys,

I wish to host a SA-MP server for myself and my friends to play in our freetine. However, my SAMP ports seem to be closed. Whenever i go to the menu of my modem and press "Port Forward" , i loose my connection for a minute or so and the page wont load.. Any help? Any other ways to forward my samp ports? I would appreciate a detailed tutorial. Thank you.
