Hello, I need multicast stream which comes on eth1 to convert and forward on eth0 so other computers and students in subnet can see it(connecting mcast stream to router or switch for everyone just mess with network and bandwidth and stream is freezing and pixeling ), (in what ever manner, but best will be as http stream so students can open stream with VLC) First I need to verify that stream is available, and for that I try with Ubuntu desktop and its working with one NIC, but with two no. After to much time without solution I decide to move to server 14.04 and UDPXY. Now I Installed Ubuntu server 14.04, with tcpdump -i I can see that mcast stream is here on eth1, can't open the stream because it's server without video card, I installed UDPXY, which is accepting mcast stream on eth1 and client requests on eth0 so they open stream like: http://192.168.2.50:5005/udp/225.224.2.3:3003 I try to open stream in VLC on Windows, and on Linux computer and nothing. The VLC log gives me the same massage like before on Ubuntu desktop.
# sudo tcpdumnp -i eth1
