I forwarded ports 5353, 12003 and 61451 in the crestron router config.? When I connect to the IP address of my CP3N using the Tesira software, Tesira will take about 45 seconds then complain and say device discovery failed.? Once I click OK, it gives me the options I usually get when biamp is directly connected to the network.? I also get live feedback when? connected to the system.
