I have a IPTV box from a Swedish operator, it's capable of playing IPTV contents. I know they are using IGMP to inform a upstream router/switch to subscribe/unsubscribe specific UDP broadcast groups.
What I want to achieve here is to monitor all the IGMP packets from/to the IPTV box. So my question is, is it possible to setup a openwrt box and monitor all the traffic? I've got a MikorTik RB450G.
