I have a problem with multicast forwarding. We buy IPTV service from a local provider and this service is transmitted to us over VLAN. I have configured this VLAN by activating the subinterface on fortigate. Our aggregate switch is located before the FortiGate. I test IP tv on one of my switch access ports. at this point, everything works fine but when testing it on the internal VLAN for the IP TV on the FortiGate it doesn't work. I use the link below to run the tests.
