Cant connect to my External IP???

[m_m]

OK, i wrote a client/server program in vb6. Actually, just the server part. I'm using a web browser to connect to the server and display the interface of the program through a web page. In other words, its a simple web server.

Anyway, when i go to "http://192.168.x.xx:7777/" in the web browser, it connects just fine. Problem is thats my internal IP, and it wont work from any other computer outside my LAN.

So i go to whatismyip and find out my external (internet) IP is 67.85.xxx.xx. I figure if i type that in the browser the same way i did my internal IP it'll connect to my app.


DOESNT WORK!!! =/ Any thoughts as to why this is??

no one has this problem?

you have to use a port that is open on the web server. try port 80, which is http

I use a port. A stated above, I am running on 7777 for testing. I connetcs fine when i use my local IP, but not with my extenral IP. Im using the correct external IP.

If you are behind a router, you will not be able to connect to your own external IP. Have somebody outside of your LAN test it.

How do I connect to my computer (from the outside) then?

[VaxoP]

you have to forward your ports

[Vishalgiri]

what you used? MSComm?

[m_m]

MS winsock control.

VaxoP - can you elaborate?

[Vishalgiri]

ok, in wsk you should have to give correct ip address and a port number usesaly geater than 3000. and same config. should be at other pc. then you have to request a connection to other one and other one should alow you to make a connection. then if you want to transfer file then you have to send and/or receive file chunk by chunk...

m_m, one question.
Are you doing the following:

Internal Comp A  
            v
Internal Comp B

Or as follows,

External Comp
           v
  Your Router
           v
Your Internal Comp

If it is the one below, then you have to use something called NAT (Network Address Translation ) to forward the ports to the correct internal computer:

IE If you are using port 1337 to connect to on the internal machine then you must forward from the Router => InternalComputerIP. I am not sure what router you have, but snoop around in it you can probably figure it out.

[alacritous]

Just as the others said, you must forward a port if you have a router. If you don't have a router, it is a firewall and you must open the port.

If you don't know how, the basic way is this:
1. Go to 192.168.1.1 (again, default/basic)
2. Login, (default is user:"" password:"admin") without quotes
3. Go to the tab "Applications & Gaming"
4. Type in the port start and end, or port 7777-7777 (only one)
5. Combo box the correct protocol
6. Put in the correct LAN address (ex: 192.168.1.100)
7. Save...

This is the basic, again, and may not work for your router.

dude what are you on?

[m_m]

Maybe I'm going about this the wrong way.

I'd rather not have to manually configure anything to be able to use my program. This software was ment for people that probably arent soo tech-savy and may be on a university network, where they can't configure any settings.

Also, on 1 LAN with 4 PC's, they may all be using my software (i.e. each pc is listening on port 7777).

You see, it gets to be a real problem then. How come p2p programs and remote software like GoToMyPC don't have any problems (assumed).

I want users to be able to access my program (their pc) from the web, without the need to actually download any extra software. I was going to have the server tell a web site their user name and IP of the server (on their pc). Then the website would find the persons IP by username (database), and connect to their home pc (really just fowarding to the url http://IP:PORT/)

Any ideas on how i can accomplish this task in a different/less problematic way?
