@Fae thanks for your answer. Sorry for the delay.
I will be waiting for the update. Will this update be valid within the Omada SDN interface?

 @Fae - the IPTV has been added / works for me on ER605 V1_1.2.0; is IPTV Multicast VLAN planned too? (as in Archer C9)

  @N_W - Could you show us your IPTV settings? I have problems with configure the IPTV on the OC200. Thanks!

Hello @Fae 

Thanks for your reply. 

See this topic on the forum:

Re:Solcon IPTV and Omada

Same here with KPN. A lot of Dutch ISP's use routed IPTV and requires IPTV_RG to be sent with DHCP Option 60 on WAN and a local DHCP-server is required for the TV decoders. A lot of them, for example KPN use both the internet VLAN (6) and the IPTV VLAN (4) for working tv. With KPN the multicast being sent over VLAN 4 and all the meta-data, guide, OTT-content and all other stuff is sent over VLAN 6.

I thought the new options would finally make it possible to install IPTV but it's so limited that I'd rather not have it. 

I also have this problem with IPTV form my ISP (KPN in the Netherlands).

Is there a way to solve this in the current Firmware of the OC200 or in a newer Firmware?

It was an exaggeration to state that IPTV works..., long story short - it does not.

Similarly to the already mentioned Dutch ISP, here in Poland the TV boxes require access to 2-3 separate VLANs the same time (Orange, 35/838/839); simple IPTV (839) activation (multi cast) allows to watch TV, but the list of channels and VOD will not work (that means after some time it will stop working, TV box will not be able to restart itself). The original router must be doing VLAN trunking, but this option is not available in ER605. As such I have connected TV directly to Orange router (Funbox), access to ER605 can be exposed on individual TCP ports in my case.
