I am trying to use Wowza Streaming Engine to convert UDP multicast streams to RTMP. The process works great when I use only one NIC when connected over wired Ethernet but the multicast streams are preventing wifi devices from streaming. What I would like to do is use two NICs, one for multicast and one for RMTP but Wowza only seems to be listening to the primary NIC. How do I configure Wowza so that it listens to publishing on one port (multicast) and serves content on the other? Thanks, Darren ---
