Bridge between 2 ethernet ports problem

RouterOS General
1

Hello All

I am facing an strange problem with my rb751G-2hnd, if I do the following:
ether1-gateway
ether2-master
ether3-slave
ether4-slave (NAS)
ether5 (media player)
wlan

I bridge ether2-master+ether5+wlan, I do this because I want to filter multicast packets on ether5 (and wlan too).
I have a NAS on ether3-slave and a media player on eth5 (there’s a PLC in between, that’s why i want to filter my iptv multicast packets so they don’t waste unused bandwidth). After some random minutes of traffic between the NAS I loose connectivity between the two devices, no ping. If i reboot the router everything works again.
The multicast filter it’s not the problem, If I remove it same happens.

If I remove ether5 from the bridge and put it as slave of ether2, everything works ok, but I cannot use the multicast filter.

Does anyone have a solution or explanation (besides convincing mikrotik to implement IGMP snooping :slight_smile: )

Thanks
Nestor

RouterOS supports multicast and IGMP. Looking to refresh my memory now whether snooping is there.

No, it does not support igmp snooping. It’s a widely demanded feature.

Yep, i wasn’t sure, but I did some google fooing and figured it out. Your right though, it is a feature that is really missing. ISP and IPTV deployers will look over RouterOS as a CPE purely for that reason. Shame, hopefully we can get MikroTik to implement soon.
