Was not able to bind socket for my public IP

Anatoli · Post by **Anatoli** » 13 Jul 2011, 16:15

Hi everyone,

I'm fairly new to smartfox and recently I encountered a problem that I can't solve

For some reason sfs binds sockets for my private and local IP with no problems, but can't bind a socket for my public IP, and therefore I can't connect to my server from different computers.

First I created inbound and outbound rules for the firewall to let sfs use any ports and it didn't work. Then I shut down my firewall completely, but the problem remains the same.

I tried to telnet my public IP, and I can't connect, which means that nothing is running on this port.

Here is the boot log of the server:

You can bind to all IPs listed in the AdminTool's Server Configurator.
You then have to configure the router to redirect the traffic from the public (router) IP to the private one.

Anatoli · Post by **Anatoli** » 14 Jul 2011, 19:43

bax, thank you for your input.

My question will probably sound stupid, but I'm new to all this and apparently I don't know some obvious things.

I am setting up the smartfox server at home, and I don't even know where the router which assigned my private IP is located. So I am not quite sure how I can configure the router to redirect the traffic from the public IP to my private IP. I tried serching the internet for it, but couldn't find anything that would seem useful for me.

However, I tried adding a new route in command prompt by inputting:

route ADD 72.95.247.214 MASK 255.255.255.255 192.168.1.24

and this new route appeared then in my routing table:

But the smatfoxserver still can't bind the socket for my public IP.
Can you tell me what I'm doing wrong?
Or if the way I'm doing it is completely wrong can you at least give me an idea of what to search for in the internet, because I feel like I'm completely lost now

Thank you in advance.

It's possible you're on a NAT and your public IP is not actually yours but shared among a subnet. In that case, your machine cannot be a publicly visible server without you talking to your ISP and have them redirect a port to you specifically.

Anatoli · Post by **Anatoli** » 15 Jul 2011, 03:52

jurekf, thanks, you were right,

I did some research on my ISP and figured out the way I can configure the forwarding on my router. I just have to go to http://192.168.1.1/ and with my username and password I can make rules for port forwardings.

However, I already tried creating many different rules for it, but I still have no luck

I still can't even telnet my public IP (72.95.247.214) on the port that I'm trying to bind (5151).
It tells me that I can't connect.

Maybe you guys can help me figure out what I have to put into the fields here to make a working forwarding rule to my LAN IP:
Protocol: TCP
Global PortStart: ?
Global PortEnd: ?
Base HostPort: ?
Direction: IN/OUT?
Port Direction: DST/SRC?
LAN IP: 192.168.1.24

I tried putting different port numbers into these fields, but I think I'm doing something wrong.

And also, after making this rule, to establish the connection with my smartfoxserver, is it enough for me to bind in server configuration just 127.0.0.1:5151 and 192.168.1.24:5151, or I have to bind my public IP somehow too?

Thanks for your help.

Anatoli · Post by **Anatoli** » 19 Jul 2011, 04:21

Hi, I'm still working on this issue and cannot resolve it.

I tried setting up forwarding, and now online checkers are saying that they can successfully connect to my service on port 5151, but I still can't even connect to that public IP using the SimpleChat example. And I cant telnet it for some reason too.

I would be glad to get some help on it.

PS. Is it fine that I can connect to my smartfox admit tool only using port 9933, even though I did bind a couple more ports on the same local IP?(127.0.0.1) I cannot connect to any of them, except the default 9933.

Anatoli · Post by **Anatoli** » 20 Jul 2011, 18:41

Hello? Anyone?

Post by **Bax** » 21 Jul 2011, 10:45

By default the examples use an external configuration file which points to 127.0.0.1. So make sure you change it to the public IP of your server.
About the AdminTool, maybe you have SFS configured to accept admin connections from port 9933 only. Check the Server Configurator module.

Anatoli · Post by **Anatoli** » 21 Jul 2011, 21:19

Thanks for the reply, bax

Now can connect to the admin tool using different ports.

But with connections I still have a small problem.

I am running smartfox server on my computer with public IP: 72.95.247.214 and the clients can easily connect to this server from different computers (finally I set up the router right).

However, for some reason I cannot connect my own computer to this server when I'm trying to connect to my public IP.
I can only connect to the server using my local IP.

I feel like I should be able to connect to it using my public IP too, or am I wrong?

Post by **Bax** » 22 Jul 2011, 15:00

Not sure, but you might be wrong. If you connect locally (SFS running on the same computer), use 127.0.0.1.

Anatoli · Post by **Anatoli** » 23 Jul 2011, 22:01

Yes, that is what I am trying to ask.

When I connect locally and use 127.0.0.1 everything connects and works well,
but when I use 72.95.247.214 - it doesn't connect. And it probably shouldn't work anyways since I connect locally, am I right?

Post by **Bax** » 25 Jul 2011, 12:14

You are right. As you are connecting locally, I think it doesn't pass through the router.

Anatoli · Post by **Anatoli** » 25 Jul 2011, 17:30

OK, I did some more research on it and now I finally figured everything out.

I cannot connect to my own public IP just because my router does not support reverse path forwarding (RPF).
That is why I can only connect to my own server using my local IP or my private IP.

Now I know what was the problem.

Thanks everyone for replies.
