Tekkit Classic Server Problems

[Rollinexcavater]

Ok so I recently began work on a tekkit classic for me, my cousin, and about 10 other friends to play on and so far everything has gone smoothly.......Except one thing. I can connect to my server using my network IP (I'm hosting and playing on two seperate computers) but no one can join when they put in my external IP 98.18.12.53. It is frusterating me and making me quite mad that I have this server running, but nobody can join it. Any help is GREATLY appreciated. Thank you
