Linksys E4200 + UDP IPTV

    Hello. I have a issue with IPTV in tomato.
    Sorry for my english :)

    My todays firmware is Toastman tomato build 1.28.0500.2 (but I tried and RAF builds).
    My main connection is DHCP. I have checked 'Enable IGMPproxy' and 'Efficient Multicast Forwarding' without that options IPTV is not working. Every 4-5 minutes of watching IPTV the image and sound is freezing. I tried to use UDPoxy without IGMPproxy - but have same issue.

    If I plug a patchcord to my computer without router - freezing disappears.

    What could be the problem?

    QoS and B/W Limiter is turned off.
    UPnP was active, but after its switching off the situation didn't change.

    I tried watch IPTV via wifi - have same issue.
    Exact time of picture freezing 4 minutes.

    Maybe anyone have ideas, what may occur every 240 seconds?

    Besides monitoring your connection with the realtime traffic graphs you could connect to your router via ssh and run
    and then try to find out whether it's a process that causes these hiccups.

    I monitored 'top', but nothing changed in process list in freeze time.

    Did you try connecting via cable? Apart from that I have no idea. Could be something completely different.

    Yes, I tried watch IPTV via cable without router - no freezing.
    I think the IPTV server does not receive keep alive packet or something like that, but I'm not sure.

    Did you try the standard firmware that came with your router?

    Of course. It does not support IPTV.

    It looks to me like you are streaming over TCP instead of UDP, that's why it freezes , and when you are not behind the router you don't have the problem. I am dealing with similar issue here, but have not found the solution yet.

    I forgot about this thread.
    I found a solution with updxy, it perfectly works with Toastman and Shibby builds.

    1. You need to disable the IGMPproxy and udpxy in 'Advanced -> Firewall'.
    2. To page 'Administration -> Scripts -> Firewall' add this line 'udpxy -S -p 4022 -m vlan2 -M 250'
    where:
    4022 - port for udpxy traslation
    vlan2 - your destanation VLAN
    250 - time of renewing the IPTV subscribe (in seconds)
    3. Enjoy it! :)
