Internet Connectivity

When networking LQ devices over the Internet, an external IP address from which the Link-Master is reachable is required as a first step in making sure Link-Members can get to the Link-Master. The external (public) IP address must be static and non-changing. Normally an Internet Service Provider (ISP) will provide external addressing in Dynamic Host Configuration Protocol (DHCP) mode.  This is not guaranteed to remain static but instead may change periodically.  This will cause linking issues as the Link-Members will not be able to reach the master if the IP address changes. Therefore, it is suggested that you purchase a static address from your ISP. Failure to do this could result in a loss of service.

To connect to an LQ unit that is behind a firewall, certain ports must be mapped from your firewall to the LQ device.  This mapping will forward traffic received on those ports from the Internet directly to the LQ unit.

• The Link-Group uses TCP port 80 (port 443 for HTTPs) for linking, data distribution and browser-based management.

• The Link-Group uses port 655 (TCP and UDP) for group connectivity and audio transmission.
