Other people can join my normal MC Servers but not Tekkit :/

[Voelkerizer]

Although i have portforwarded manually, used Simple Port Forwarding, and used Hamachi, people simply cannot connect to my Tekkit Server. They can easily connect to my Bukkit Server and Normal MC Server using all of these port forwarding options.

yes, i tried putting the server ip, in properties, blank and with the ipv4 address.

yes, i know how to go onto 192.168.1.1 and change the port.

yes, i used 25565 TCP/UDP

yes, we all do have the correct build selected.

yes, we have the Technic launcher unblocked via properties.

yes, i went into my advanced security settings and manually unblocked Minecraft.

i can connect easily but others can't.

help.

What my Properties looks like right now.
