Hello Everyone!

I've got a network built with two TP-Link devices: FW/Router ER605 v1 and switch TL-SG108PE. ISP provides me internet and IPTV on dedicated ONT ports - internet (port 1) and TV (ports 2&3). To get internet and TV in one room I had to create VLANs (VLAN1 for internet and VLAN2 for TV) with single trunked port. VLAN2 (TV) is done only between LAN ports in FW/router and switch. It doesn't go out to WAN.

ISP provides IPTV service as multcast. I don't know ports for this service. Using VLANs between LAN elements I can get IP from DHCP, EPG and other information on set-top-box (probably it is a web service), but I can't get a video/sound.

I suppose that multicast service is blocked by FW/router on LAN ports. I've configured access control list (LAN->LAN, any traffic, any port, ALLOW) and IGMP, but still same.

I can see that multicast services are available on switch:

Help!

Best regards
