Prevent IPTV Multicast Flooding

Hi,

I recently just bought a RB260GS, so that my IPTV box can be placed anywhere in the local network. Here are the current network diagram and configuration.

The main problem is, every client is flooded with IPTV multicast, even though it has different VLAN (client doesn't have any VLAN, only IPTV network is on VLAN). RB260GS is used exclusively to strip VLAN tag, as the STB doesn't support VLAN. Until now the network is running perfectly without problem, only the LAN is flooded with multicast.

And, Mikrotik cannot get IP address from IPTV network DHCP, so I think using IGMP proxy is impossible ?? Although using IGMP proxy method is better for me since I will not need the RB260GS anymore.

Thank you

to my knowledge you can't mix vlans and unmanaged switches.

You can mix them, they just will not care about VLANs, so that is an expected behavior: multicast flooding on all ports...

The problem is, wireless client is also being flooded with the multicast.

Is there anyway to do IGMP proxy to prevent this?

I have an idea like using pptp tunnel to isolate network? Such as rb951g have pptp server, and use hap lite as pptp client, and remove rb260gs. However, I want a tunnel without any encryption, is there any?

IPIP for example. PPTP can be used also without encryption.

Guess there should be phisical reasons not to do this, but... wouldn't it be possible to wire first rb951g (the one plugged to the modem) to the second rb260gsp directly??

Why do you think you cannot use IGMP-Proxy?
