5.6 Linking over Internet or WAN
When linking over Internet or WAN, the IP addressing of the units becomes more
complicated because the units use external addressing and port-forwarding to
navigate firewalls. The LQ units must be able to reach the Link-Master.
Figure 5-3 Linking over WAN or Internet
The Link-Master uses TCP port 80 for management and TCP/UDP port 655 for
audio. You will need to create port-forwarding rules within your firewall to make
these ports externally accessible to the Link-Master device.
The Link-Master’s external IP and port will need to be configured within the
Network page of the CCM.

Link-Master internal IP: 192.168.1.100
Link-Master external IP: 34.50.16.7

LQ #1
LQ #2
External (public)
IP: 34.50.16.7
Link-Members are configured to
join the Link-Group using the
Link-Master's external IP and
management port.
You might have to use port-forwarding. See
7. Internet Connectivity for more
information.
Example port-forwarding at firewall:
Port 80 forwarded to 6300
Port 655 forwarded to 6301
