Currently I am trying to wake up my desktop computer at home from elsewhere. I am approaching it as the following:
In my TP-link router I openend the UDP 9 port and forwarded it to the local IP of my desktop computer (192.168.0.103).
Filling in my public IP and the MAC address of my desktop on this website: http://www.dslreports.com/wakeup.
Press Wake Up!
Waking my desktop up in a LAN environment works fine, but via the internet it doesn't work. I would really appreciate suggestions that can help me out.

I am new on computer networking. I install Apache server on my Ubuntu desktop computer. And i made a website on this PC. When i connect my PC With internet using a dial-up (Mobile Broadband) modem then i find my public IP or IPv4 address on my connection status. When i type this IP address on my PC browser it runs my web-app or website. But when i use the same IP address on my another computer that can't open my website. I also try IIS server with windows server and windows desktop. My public IP work only my PC but not other PC. Can anyone tell me what is the way to connect my PC or Server with internet and people can access my web-app from internet.
Did you try ping? If you cannot reach the server using that method, your connection problem has nothing to do with the web server. That's a start :-)
I have a raspberry pi, with samba configured properly. It's IP address is xx.xx.xx.xx and the proper ports are forwarded. I can access it from my mac by doing open smb://xx.xx.xx.xx but I do not know how to do it from a Windows computer. I have tried \\xx.xx.xx.xx\sharedfolder in a browser and mapping network drive at \\xx.xx.xx.xx\sharedfolder which crashes my computer when using "Map network drive."
I know this is a really stupid question, but I have found no help through google searches, any help is highly appreciated.
You basically open the Start menu, search for run, click enter, and then type in this \xx.xx.xx.xx.
I can connect my iPad directly to my Windows 7 laptop using a Win7 adhoc connection and the laptop's internal wifi. That much works. (I tried the alternative of connecting via a wireless router, unsuccessfully.)
Now that the connection is made, I need the iPad to access the XAMPP Apache server that's running on the Win 7 laptop.
I run 'ipconfig' on Windows to find the IP address assigned to the laptop, type this into the iPad's Safari browser address bar, and get "Unable to connect to http://www.192.168.2.5 because you are not connected to the internet."
The 'http://www' is inserted by Safari, I did not type that in.
I also tried including the port that Apache is listening on: 192.168.2.5:80 , with the same result.
I do NOT want to connect to the internet at large (I don't have the two wifi cards necessary to do that), but only to the local Apache server on the Win 7 laptop.
Another answer describes doing this with Bluetooth. I do not have Bluetooth available on the laptop.
The iPad is running iOS 7.1.2.
I've tried the usual tricks on the iPad, resetting Network Settings, turning on/off Airport, etc. Still, Safari insists on inserting 'www' in the address and denying the connection.
How do you connect an Ipad2 to a localhost server running on Windows 7 without having a simultaneous internet connection?
How to enable Hyper-V to connect VPN for external internet access in Windows 8?

Please advice.
Thanks.
MSDN has a troubleshooting page for the Windows Phone 8 emulator. Perhaps you can find related info there. Something like this might help:
Cannot connect to Internet destinations
The Windows Phone 8 Emulator uses the HTTP proxy settings from the host computer. If you can’t access Internet resources from the emulator, check with your IT administrator to make sure that your proxy settings will work with the emulator.
If your network’s proxy servers are unavailable or malfunctioning, it might be possible to restore connectivity for the emulator by disabling automatic proxy detection on the host computer. However this only works in certain network configurations.
To disable automatic proxy detection on the host computer
On the host computer, open Internet Options from the Control Panel. The Internet Properties dialog box opens.
In the Internet Properties dialog box, click the Connections tab.
On the Connections page, click the LAN settings button. The Local Area Network (LAN) Settings dialog box opens.
In the Local Area Network (LAN) Settings dialog box, deselect all the check boxes. Click OK twice to close both dialog boxes.
Restart the emulator and retry the connection.
Also this MSDN blog-post can be helpful: Why can’t the Windows Phone Emulator go online?. Useful part of the article:
As you see, clicking the “>>” on the bar parallel to the Emulator will open a small window with 4 tabs. The last tab is for “Network”. To explain in simpler terms, there are two adapters here – one is for internal use by Emulator and other is for external network connectivity. Each adapter will have an IP address (IPv4) associated with itself. The one of our interest is under Adapter #2.
I have erased out the IPv4 address that is assigned to Adapter #2 (Yellow box), but you find that the IP assigned here starts with 169.254.x.x…., then Bingo! - we have figured out the problem. How?
The IP addresses starting with 169.254.x.x …. Are usually the self-assigned default addresses to a device and not really helpful to get the device to go online. This IP should either be a static IP or the one assigned by the DHCP server (if you have one in the environment) for the device to be able to connect to external networks.
Hope this helps.
I have a problem using GCDAsyncUdpSocket over internet. Everything works fine when I am doing test on my local computer.
I try to to send UDP message between a computer connected to internet with a 3G key and an Ipod connected through wifi. Unfortunately the message are not transmitted. I tried to do the same test with the example of GCDAsyncUdpSocket : UdpEchoClient and UdpEchoServer, and it is also not working.
To know the address IP of my computer with the 3G key, I looked on system preferences -> network, I also looked on http://whatismyipaddress.com/ , I saw that the adresses were different. With both it is not working.
My Ipod connected through wifi is behind a NAT/Firewall, but according to this website : https://www.gotroot.com/blogpost4-Why-your-should-never-forward-UDP-out-of-your-firewall It shouldnt be a problem.
Is it possible to send message between 2 devices without opening any port?
Why do you have two different IP addresses on my computer with 3G?
