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.
Network & Firewall Overview 3.2 3.2.1 Firewall Configuration Overview By default the Lake Controller Installer creates exceptions for all Lake applications, so manual configuration should not be required. If all devices connected to the network are not appearing as expected, it is possible that a firewall is enabled and is blocking these programs from obtaining network access.
Network & Firewall Overview When using the standard Windows 7 firewall and an alert similar to that shown in Figure 3-2 is displayed: 1. Select checkboxes to allow the Lake Controller (or other Lake application) to access both the Private and Public networks. 2. Tap Allow Access. When the Lake Controller or other Lake application opens without this warning, but connected Frames cannot be identified on the network, the application firewall settings can be verified manually: 1.
Network & Firewall Overview If using automatic IP address allocation, please ensure your Ethernet switch and/or Lake devices are turned on and connected to your PC for a minute or so (Windows XP - generally faster on Windows 7) before starting the Lake Controller. This allows Windows time to correctly identify your PC’s IP address, and therefore allows the Lake Controller to communicate properly when it scans the network.
Network & Firewall Overview 2. Select the appropriate network connection (Local Area Connection or Wireless Network Connection) to configure, then select “Change settings of this connection” as shown in Figure 3-5. Figure 3-5: Selecting Wired Network Connection Although this tutorial uses Local Area Connection as an example, the principles also apply to Wireless Network Connection. 3.

Network & Firewall Overview 3.6 Dante and AES67 Digital Audio Networking Dante and AES67 provide multi-channel digital audio networking over standard a standard Ethernet network, alongside control data for the Lake network. Various topics relating to network configuration are summarized in this section; for further details please refer to associated Dante literature available via: Start > All Programs > Lake Controller vX.
Network & Firewall Overview 3.6.3 Using Dante with Wireless Data Control or Low-Bandwidth Devices Dante (Digital Audio Networking) technology requires a reliable 100 Mbps (or faster) network to operate, and therefore cannot operate via a wireless transmitter/receiver. However, in most Lake networks, it is likely that wireless control of the Lake devices will be required on the same network that is transmitting and receiving Dante digital audio signals.
Network & Firewall Overview 3.6.4 Dante with Quality of Service Ethernet Switches The use of an external Ethernet switch with QoS (Quality of Service) is strongly recommended when using Dante digital audio over your Lake network. Dante uses standard network QoS techniques available in off-the-shelf Ethernet switches to prioritize clocking and audio traffic, and to allow non-Dante devices such as personal computers to share a single network with Dante devices.
Network & Firewall Overview 3.6.5 Recommended Network Topologies When Using Dante The use of an external Ethernet 100 Mbps switch with QoS (Quality of Service) is highly recommended. It is also recommended that each device has its own direct connection to that switch. Where switches are connected together, this should be achieved via a gigabit fiber or copper connection. Figure 3-14: Recommended Network Topologies Two Lake devices may be daisy chained together and run Dante.
Network & Firewall Overview More than two Lake devices should not be daisy chained together when Dante is being used. Figure 3-16: Do not daisy chain more than two Lake devices when using Dante The use of Dante across wireless networks as shown below is not supported. Figure 3-17: Do not use Dante across wireless networks Please refer to the Audinate document AUD-ANO-QoS Recommended Network Topologies for further details regarding ACL packet filtering.
