I have configured Routed IPTV using the guide below. I am able to watch television, but after a while (5 minutes or something like that), my television displays a message saying that I lost connection between the IPTV-receiver and the modem.

I'm using a XG7100 with IGMP proxy. After I disable and re-enable the proxy, the television starts working again.

Does anyone here know how to solve this issue, or have a clue in where this problem might be in?
