the external IP is 89.256.12.56 (i.e) and the internal IP is 192.168.160.11(i.e)
How can i connect to that computer, i mean , whats the address i should use? 192.168.160.11@89.256.12.56? Do you understand me? Can you help me?



Thanks in advance.

What are you trying to do here my friend, in oder for us to give support you need to give more details about the situation

[xaramaneco]

I made a file transfer program with a server and a client.
I put the server in my one of my friend's computers , he has a LAN of 3 computers in his house , 192.168.160.2 , (192.168.160.3) <- (the computer where i put the server) and 192.168.160.4.
If i wanted to connect my client to his server using my computer (obviously not on his LAN), what address should i use?
If i was on his LAN i would directly use 192.168.160.3 , but i am not , so how will i connect?

To connect to his network over the Internet, you'll have to consider something like a VPN, and also there will be some configuration of any router's in the path as well.

[xaramaneco]

Well it's not really that.
Like, if i wanted to use the PING command on CMD what should i use as IP...
Ping xxx.xxx.xxx.xxx
What should the x's be?

[johnwill]

His public IP address is the thing to use.

[xaramaneco]

You mean the external IP address? Isn't that one used by all computers in the network? If not , how can i get his public IP?

You could have your friend visit either www.whatismyip.com or www.ipchicken.com and tell you his IP. However, this still won't allow you to connect to the server with just his IP, you'd need to configure his home router (either opening ports, forwarding ports, or triggering ports) to forward the connection from your computer to the server on his network. Not knowing how you wrote the program or how you're telling it to connect to the server I couldn't help you much more. Sad to say I wouldn't be able to provide much more help even if I did know this information. If your program uses a port it might just be as simple as telling his router to forward that port to the server and that should solve it. Sorry for the long winded reply of little help :) Best of luck

I've wrote it in VB. It has a textbox for the ip and the port is in the code.
However, i dont have access to the router's configurations because i dont know the access password. It's not the default one...

[xxfallacyxx]

most if not all routers have a reset to default function, usually holding in the reset button for 15-30 seconds while powered on or something like that. A quick google search with the brand and model should reveal that. Of course thats only with your friends knowledge and permission should you do that lol. Also be sure to ask if maybe said friend has any special setup for their network, don't want to open up a can of worms. If that all goes well then you should be able to forward the ports in his network to the server computer and simply tell your program to connect to his external IP address and the router will forward everything to the server. Best of luck with that, let me know how it works out

[xaramaneco]

I understand, too bad i don't have physical access to the gateway :/

[johnwill]

Connecting to another location through routers and other gateways requires some configuration of the entire path, that's the way it works.
