Network & Firewall Overview
3. Network & Firewall Overview
This chapter provides an overview of key requirements in terms of firewall configuration, wired and wireless
network configuration, and Dante audio network configuration. The separate Lake Network Configuration
Guide and Dante configuration literature that is included as part of Lake Controller installation should also be
consulted for additional information.
3.1 Ethernet Overview
The TCP/IP protocol suite is structured in layers as illustrated in Figure 3-1. The link layer is Ethernet and is
responsible for connecting to the cabling and Ethernet switches. For communication to occur, each device
must have a valid IP address. The IP layer uses these addresses to route packets between devices. The
transport layer provides flows of data and is used by applications to communicate with each other over the
network.
The Lake Controller uses UDP messaging to communicate with Lake devices on the network. Network
setup and configuration is fast and easy; simply hook up all the devices on the network, and the
Lake Controller software detects and communicates with all devices as required.
Figure 3-1: TCP/IP Protocol Suite
Lake devices are configured to use Automatic Private Addressing which allocates IP addresses from the
range 169.254.x.x. In most scenarios, this automatic allocation setting will not need to be changed. How-
ever, if the device is integrated into a sophisticated network configuration, the IP address allocation method
can be changed using the Lake Controller software.
