Problem with two NICs

[astlin]

Hi. My server has two NICs - NIC1(eth0) and NIC2(eth1). I receive TS multicast from NIC2, grab some programs from it and trying to send them to NIC1.
This is my vlc launch line:

vlc -vvv --miface=eth0 udp://@239.193.1.51:6001 --ttl 12 --programs=14802,14803,14804 --sout-standard-access=udp --sout-standard-mux=ts --sout \
'#duplicate{dst=std{dst=239.193.1.81:6001},select="program=14802", \
dst=std{dst=239.193.1.82:6001},select="program=14803", \
dst=std{dst=239.193.1.83:6001},select="program=14804"}'

vlc receives stream only if i add route: route add -net 224.0.0.0 netmask 240.0.0.0 dev eth1
but it doesn't transmit it to NIC1. i thought --miface or --miface-addr option would resolve this problem, but alas. help, please
