Hi @Tux0ne 

 

I read your support notes about similar problems but despite below configuration still have the issue “TV box saying no signal on channel when put behind firewall/router”

 

The current set-up is the following

 

Devices : Swisscom  router Internet-Box 3 (IB) -> USG -> Unify Switch -> Unify Access Points  

 

IB (set-up)

 -------------

192.168.100.1 and subnet mask 255.255.255.0

Activated DHCP range (192.168.100.101 to 192.168.100.220) 

Activated DMZ for device and linked to Firewall-Unify

 

USG (set-up)

 -------------

USG 192.168.1.1

USG, connect to IB 1 gbps LAN port

 

UniFi network (set up)

-------------

Enabled IGMP Snooping 

Enabled Multicast Enhancement (IGMPv3)

Enable Multicast DNS” set to ON

 

Blue-TV set is connected by network cable to a switch

 

Can you please advise what is missing? Thank you very much in advance for your comments
