I have created a TCP server using node.js
The server run on port 8xxx.
I've tested the server using telnet on iPad, it's OK.
The computer which runs the server and the iPad use the same wifi network.
The wireless router is connected to a VDSL Modem which is connect to the Internet.
How to telnet the TCP server using another computer not in my LAN?
I'm new to networking. Please show me how :) Thanks!
P/s: Sorry for my poor English.
If there is any firewall blocking incoming connections, you should be able to connect to your TCP server with your WAN IP and the port you configure.
You can find you IP by visiting website like: http://whatismyipaddress.com/
Then, try to connect from remote computer with something like telnet [YOUR IP] [PORT]
If connection don't work, please disable every software firewall and/or material firewall and it should work properly.
In this case you will need the public IP for your computer (Server). Normally the public IP changes every time you login to the ISP client. You can find your IP by using whatismyip.org.
Now, the other machine should also have internet connection. Then telnet using the public ip that you got from whatismyip. It will work.
