Server can't connect from other networks

People can't connect from other networks to my server, i can even with my mobile phone in house connect to my server. Do someone knows why?

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3. using System.Collections.Generic;
4. public class Server : MonoBehaviour {
5.     //The ip adress
6.     public string IP;
7.     //the port
8.     public int Port;
9.     //admin
10.     public bool admin;
11.     //first
12.     public bool First;
13.     //user
14.     public bool User;
15.     //username admin
16.     private string admin_password;
17.     //username admin
18.     private string admin_username;
19.     //username
20.     public string username;
21.     //password
22.     public string password;
23.     //list with username's
24.     public List<string> usernames;
25.     //list with password's
26.     public List<string> passwords;
27.     //list with emails
28.     public List<string> emails;
29.     //network view
30.     public NetworkView networkview;

Why they can't connect?
Can you provide more info about this? Have errors in your app?

 

Chances are you need to port forward your router or use NAT punchthrough.

When you create a listener you can access it from your network using the same port number because you specify the IP address but because your router will have a different IP that serves multiple devices it translates port numbers to avoid collisions when 2 PC are listening on the same port number. Port forwarding forces the router not to do that and punchthrough just scans your router until it finds the correct port.

Alternatively, if you provided them with and IP beginning with 192.168... then you've given them your internal IP address not your external IP address. You can find your external IP here.

 

well, is a port forwarding something that has been already installed or do i need to do that?

The connection request to 94.***.125.***:25565 failed. Are you sure the server can be connected to?

 

Ok so your IP looks fine, and considering you don't know what port forwarding is I suspect it's that!

Google it. It's a system to stop your router changing the port number you assign so it's easier to access from outside your network. It's not software rather something you need to configure on your router.

If you're planning on your players hosting their own server then you need to look at Nat punch through.

Well, iam the only one to start the server, but what if my IP is a dhcp?

 

That shouldn't make any difference. Your router will still change the port. Specify the port forwarding rule using your pc's name rather than its IP if you can, otherwise you may need to assign your pic a static IP to do it.

 

And how do i do this

 

It depends on your router, I can't help you from here you just need to Google how to do it.
