Note: If you see an error message in the UPnP section, or you changed some router settings in the meantime, it might help to disable and re-enable the RemoteTap server in order to re-start the UPnP process.
Step 2: In RemoteTap on the iPhone, create a second profile for your Mac and use the external IP address of your Internet router as the IP/DNS. You can check your current external IP address here (some ISP use web proxy server, in such a case, use the “Proxy Reports IP as” value as IP/DNS) .To avoid having to change the IP/DNS all the time, use a dynamic DNS service described here.
Step 3: In case your router doesn’t support plug and play, port forwarding needs to be configured manually. Unfortunately, each router comes with a different user interface. The feature required is usually called “Port Mapping”, “Port Forwarding”, or “Application Sharing”. Below are the setup instructions for some routers models:
• Apple AirPort Base Station (new 802.11n)
• Apple AirPort Base Station (old 802.11g)
• DLink DIR615 Wireless Router
• DLink G604T Wireless Router
• Netgear Routers
• Linksys Routers
A good port forwarding resource for many more routers is available at http://portforward.com/routers.htm.
Step 4: If the Internet connection still fails, please follow the troubleshooting steps.
