Cannot setup Tekkit server (Problem included)

[Tris]

I have Port Forwarded and i set up a static IP, however The server still wont run unless I use my Local I, which is unusable by other unless I use a hamachi server, which I dont want to use. whenever I use my Public IP, the server tells me this: (my console log is broken so i had to type some of it up)

[WARNING] **** CANNOT BIND TO PORT!

[WARNING] The exception was: java.net.BindException: Cannot assign requested address: JUM_Bind

[WARNING] Perhaps a server is already running on that port?

and then it gives me a bunch of [sEVERE] errors

I dont want to use hamachi so please dont tell me to do so,

i have 16gb of ram and the server is using 4

Any help would be greatly appreciated

use your local ip (it will be something like 10.0.0.13) in ur server config file and use this to conect to your self.

then hand out your external ip (it will be something like 111.162.10.124) this is wat other players use to connect to you.

(Note: it is the same as setting up a vanilla server use youtube to help you)
