Hello there, I'm pretty new to network security, but I would like to know how can I block a certain external direction. The thing is, the direction is an IPTV channel, and I have read it is ruled by IGMP proxys, so it can not be blocked using simple Incoming IP-Filtering. The router I'm working with is Comtrend WAP-5813n, the one my ISP installed. And another side of the story is, I can active what is called "LAN side firewall", and all traffic is blocked, by meaning all, I mean even my access to the router via web browser or telnet. So I don't really know how to set it properly. By reading other threads in this forum, I have seen the level of knowledge here is much higher than mine, so please if you consider other aspects of the issue I'm trying to solve, please tell me. Here is the configuration page of the IP-Filtering I said before. I also do not know what Interface do I have to set, I have tried with ppp0.6 but I can still watch the channel. Thank you.
