    This is the best guy on the Internet on Unifi software, he really goes in detail on any Unifi option. I don't think that even unifi guys know more than him :). Thanks for the video.

    Great video as always. Couple of quick questions:
    1 - Which release of switch FW were you running ? If not EA have you tried that ?
    2 - Would you generally recommend multicast filtering / IGMP snooping being enabled for surveillance VLANs (Cameras + NVR) as opposed to just media networks (AirPlay etc) ?
    Thanks

      1) 7.1.26. No, I don't use EA firmware.
      2) For a VLAN you don't expect multicast traffic, the only benefit of enabling IGMP Snooping I can think of is to prevent potential DOS attach by using multicast floods.

    What website were you using @8:01 ?

      8:01 is not a website. It's my slide for this video.

    I’ve read that the routers can now accept multicast IPTV from the WAN side. Have you checked this yet?

      @@sanpietroprogettista9887 I don't use IPTV, but may check it with VLC if I know where to enable it... I am not aware of a setting for it.

      @ under WAN in internet options there is an iptv streaming option.

      I tried it today but could not make it work.
      - I started a video source from WAN.
      - I enabled IGMP PRoxy on WAN port.
      - I started video client from LAN.
      - I monitored both WAN and LAN IGMP tragic.
      From LAN, I could see the IGMP packet related to the IGMP group I spesified, but from WAN I did not see the packet. To put it another way, I don't see the effect of a "proxy".
      I cannot figure out why.
