Cant connect to host through public IP.

When i try to connect to the host with my public IP it doesn't connect, It doesn't return any error messages or warnings, I have port-forwarded and tried disabling all firewalls but it still wouldn't connect, so what is likely to be the issue here?. here is part my script for the connections:

Code (CSharp):

1. void CreateServer(){
2.         manager.networkPort = 7777;
3.         manager.StartHost();
4.     }
5.  
6.     void JoinServer(){
7.         manager.networkAddress = serverIP.text;
8.         manager.networkPort = 7777;
9.         manager.StartClient();
10.         Debug.Log (manager.networkAddress + ":" + manager.networkPort);
11.     }

 

Did you setup network firewall for your port?

 

Yeah, i tried this but it still doesn't work though.

 

Have you run the server and client on the same machine and tried the loopback/local IP address, just to be sure you can connect at all? ie. 127.0.0.1

 

Yes i can connect through my local IP, but not though my public IP which tells me that its working but i just cant connect through the internet.

 

Update: just in case i wasn't clear on what i want to do, I want to create a master server on a machine at home (until i can afford to rent a server) which other clients can connect to because i don't want to use unity matchmaking for these reasons:
1. It requires a client to run a host so when they quit the game shuts down,
2. I want to support up to 200 players in each game and unity free matchmaking only supports 20.
3. The type of game i want to create is a small MMO game and i don't think using matchmaking is the best option for that.
4. I want to keep it open 24/7 even when no-one is in the server.

 

Another possibility is your ISP may block the ports you are trying to connect too? Are you _sure_ you have the right public IP address? Are you _sure_ you have your NAT tables setup correctly? Can you connect, on your LAN, from one client machine to the server machine, using LAN IPs? Those are things I would check, double check, etc.

Good luck!!

 

I'm sure my networking is working properly because i have started ports for other games like Minecraft for example where i successfully connected through my public IP.

 

... Still having the issue.

 

Did you tested with a port scan from an external source. Or an online tool like this:
http://www.yougetsignal.com/tools/open-ports/

 

It says the port is closed.

 

Then you should check your modem/router/firewall settings. Do you use port 7777?
What rules do you have defined on your router? In the video the from tungchengvn around 6:40 is what you have to check on your router. Maybe you can post some of your settings here.
I don't know how Minecraft handles networking. Maybe it opens the port on the router with UPNP.

 

- I Disabled my firewalls when i was testing the connection.
- I used port 7777 but i also tried other ports.
- Rules for router?.
