Router Port Forwarding - Talkswitch CT.TS005.003904 User Manual

If your router does not support DDNS, download one of the applications specified on
www.dyndns.com. To update the DNS servers, the application needs to run on a PC
connected to the same LAN as the TalkSwitch system.
3. If you selected Static public IP address, enter the Current public IP address from your ISP.
Leave the Fully qualified domain name box blank.
If the TalkSwitch unit is not behind a router, or if a private virtual network is used, the
public IP address should be set to the local IP address of the TalkSwitch unit acting as
local proxy.
Note that it will take up to one minute for the new static public IP address to take effect.

Router port forwarding

The Router Port Forwarding area displays the type of gateway device (i.e. the type of router), the
IP address of the gateway (i.e. router), and whether router configuration is required.
A router is a gateway between the local area network and the Internet. Most routers have a
firewall to block unwanted data from the Internet. For voice data to reach the TalkSwitch system
through the firewall, port forwarding is required. Port forwarding allows the router to map ports
to the IP addresses of the TalkSwitch units. Valid Internet data will use the ports to go through
the firewall to the TalkSwitch units.
If you are setting up external IP extensions, a TalkSwitch VoIP network, or a VoIP service that
doesn't handle port forwarding, port forwarding is required.
If port forwarding is required, and your router supports uPNP (Universal Plug and Play), ensure
uPNP is enabled. The TalkSwitch system will use uPNP to automatically set up port forwarding,
and the Automatic (uPNP Enabled) link will appear. No router configuration is required.
If port forwarding is required but your router doesn't support uPNP, or automatic port
forwarding doesn't work, the Manual Port Mapping Required link will appear. You will need to
configure the router as described below.
1. If required, click the Manual Port Mapping Required link. The Manual Port Mapping
window appears. It lists the packet type, port number, IP address and protocol of each
required port.
