I have a problem with %subj% -- I'm trying to pass IPTV (IP multicast) from WAN to local network, the router is configured as gateway, with firewall and IPS switched off and with multicast passthrough switched on. On the client side I'm using VLC.
After reboot, VLC is able to play any multicast stream for about 30 seconds. After that time, packets coming from router stop (I examined this using WireShark). Sometimes, the receiving continues after another approx 30 seconds, but it stops again and forewer. If I switch streams (if I use another IP multicast address) before the first 30 seconds elapse, I can keep multicasting alive for longer time.
Do you have any hint? Now it is a big problem for me, is not there some new FW being prepared (I have 126.96.36.199)?
