NAT Settings:

In most cases, a LAN (Local Area Network) does not assign a unique global IP address to each client's machine. In order for you to use Gphone, you must adjust your "NAT settings" in order to receive calls from buddies across the Internet.

Gphone supports the use of multiple machines inside a LAN with a Global IP. (Many IP technologies do not).

Ports used for Gphone (Default):
UDP 6701: Used for sending/receiving voice packets. Required for voice communication.
TCP 600: Used for transferring files
UDP 5060: Used for receiving signals. Required for voice communication.

NAT settings can be called different names depending on the manufacturer of your router. They could be called "Port Forward", "IP Masquerade" "IP Address Converter", or "Virtual Server". For example, they are called “Address exchange setting” in the BroadStation manufactured by Meloco.

How to configure router (Linksys)

Here is an example of how to configure a router using Linksys - Instant Broadband Series.

The following process forwards (opens ports) UDP port and TCP port to the following terminals under a Linksys Router. Even when you are using only 1 terminal, if a Router is installed, UDP and TCP ports are closed. So make sure to forward (open) the ports needs to be used within the Router settings. Gphone's default setting for these ports are: UDP 5060, 6701 / TCP 600. If your network has one router and multiple terminals, please make sure that each terminal is assigned to unique ports. If the same ports are assigned to multiple terminals (computers), the packet sent to the port will self-destruct.
