PLEASE HELP SOMEONE

[OptimusMoJo]

i have been trying to make a tekkit classic server(free of course) all day and i have had no luck. Ive made servers before but never tekkit classic. Ive looked up countless videos hoping to find a helpful one but still i find nothing. it may be because port forwarding with my internet is wierd but i dont know. I have At&t internet by the way. But could anybody help me with this. Its getting frustrating and i dont know what else to do.
