How to connect 100 computers together?

Why can't people connect to my Minecraft Server?

• I have a netgear router. I followed a tut on youtube b/c i got a new internet awhile back and i knew I've seen many solutions to this but none of them have worked and it's frustrating. I knew how to do it on my old router but i got a new internet recently so. My start and end port are as follows for my mcserver service on netgear. start = 25564 end = 25566 my ip is my computers ip which is 197.168.1.7 i connect using 197.168.1.7:25564 i told him to connect using my external ip with the port but it didn't work. 76.100.10.144:25564 but when others try to connect using my external ip it says they can't r each server. I checked on port check to see if it's open it says it is when my server is up so.. I tried this method because the entering same port thing didn't work for some reason b/c it wouldn't open so i was looking for results and i found a tut that told me to do it this way. Maybe i told them wrong ip.. idk but please someone help.. 76.100.10.144

• Answer:

  So I've created Minecraft hosts before, but for some purpose nobody can hook up but me now. I am using Hamachi and they can all go to my system, but when they try and be a part of from my IP, it basically doesn't let them be a part of. My AIM is PotatoLotion and I would significantly appreciate any help. Everything is designed properly, so I have no concept what could be incorrect. We are all on the latest edition of minecraft as well.
