We generally recommend only forwarding what you need, but if your device is not in the above list or things don't seem to be working for you, below you'll find a list of everything combined that may help.

Forward Ports for RTP
When you use RTP you might need to forward some ports in your router. By forwarding ports you allow connection requests coming from the internet to be directed to RTP.
Routers are not designed to allow incoming network requests. Forwarding ports can work around this limitation.
Before Forwarding a Port
Make sure that you know these things before forwarding a port:
- Your router's internal IP address.
- Your phone's internal IP address.
- A list of TCP and UDP ports that need to be forwarded.
Locate Your Router's IP Address
The easiest way to locate your router's IP address is to run our free Router Detector utility. It is part of our Network Utilities suite of tools and is free for you to use it.
If you do not want to run the software, you can follow our Find Your Router IP Address guide.
Forwarding a Port for RTP
You can use our Network Utilities software to automatically forward ports for you. Our Network Utilities software allows you to add port forwards and also remove them when you no longer need them to maximize your network security.
You can also choose to set up port forwards manually. The normal process for forwarding a port is:
- Begin by logging in to your router.
- Locate the section in your router that deals with port forwarding.
- Type your phone's IP address into the correct box in your router.
- Put the TCP and UDP ports for RTP in the corresponding boxes in your router.
Some routers need to be rebooted in order for the changes to be saved.
You can choose your router from our list to see exactly how to forward ports for RTP:

That is the process required to forward ports in your router for RTP.
