Telephone base installation
If you have problems getting the ip8300 installed properly, first verify that you have the device physically
installed properly. Then try rebooting the base by unplugging the power and plugging it back in. Some
routers require modifications to their firewall settings to allow the ip8300 to access Internet content.
In this case, we recommend that you forward TCP port 5060 to the IP address of the ip8300, or configure
it as the DMZ host. To find the IP address of the ip8300, check the DHCP log for your router. For detailed
information on checking DHCP logs, setting up port forwarding, or DMZ host configuration, refer to
your router's documentation or call the manufacturer for help. If you continue to have problems, refer
to the Troubleshooting section on page 92 for additional information relating to setup.
The following diagram illustrates a typical network layout after the ip8300 has been installed.
