Multicast VLAN setup on GS716T v2
I would like to setup a GS716T v2 so that port 1 is the internet source from the router. Port 2 goes to a Computer, Port 3 has an IPTV feed (Multicast UDP) which is accessible by the computer, Ports ...
Trouble is that each VLAN does make-up a dedicated network.
The switch can't magically "merge" the IPTV network with it's DHCP IP range (probably supplied direct by a carrier side NAT), and the IGMP Multicast traffic with your router NATed LAN and it's locally router served DHCP and IP subnet.
For the very same reason (plus some more), it's not possible to have more than one network (read VLAN) untagged on one port. Similar, only one PVID - that's the VLAN incoming untagged frames are assigned to. Of course you can configure a VLAN trunk on a switch port (or a LAG), but all VLANs must be tagged, just one can be run untagged.
Not sure what kind of IPTV network and implementation you talk of. Most of IPTV network implementation make use of Unicast UDP if using a Web browser, also for live TV. Simply because there is no IGMP Multicast client on a common Web browser. IGMP Multicast is typically used with the set-top boxes only.
Lack of more details, it's a little bit difficult to help beyond of this.
