Allowing Concert to work with other UDP and TCP ports other than 6001
Most Clear-Com IP products either use easily configured TCP/UDP ports, or must use a range to perform their functions.
Concert only uses one port (6001) for data and audio to/from clients, but it is not easily configurable. We can use the built-in Concert server firewall to internally redirect additional ports to 6001, allowing more ports to be used.
At the command prompt (or in the Terminal application in Desktop mode) add the following:
iptables -t nat -A PREROUTING -i eth0 -p tcp --dport 6002-j REDIRECT --to-port 6001iptables -t nat -A PREROUTING -i eth0 -p udp --dport 6002-j REDIRECT --to-port 6001
In this example, 6002 can now be used by Concert clients. To use the second network card, change eth0 to eth1.
A port which may be open is 443. Do not use port 80, as this is used by the web GUI.
