Hi @piero
Welcome to Zyxel community.
Here is topology:
Multicast Server(192.168.1.X)-------USG60#1=====[VPN]=====USG60#2------Client(192.168.10.X)
Please go to make sure your configuration first.
On USG60#1:
LAN interface: IGMP setting is upstream.
VTI interface: IGMP setting is downstream
Create policy router for IGMP traffic is able pass into VIT interface.
e.g. Destination IP: multicast group IP, NextHop: VTI interface.
On USG60#2:
LAN interface: IGMP setting is downstream.
VTI interface: IGMP setting is upstream

Hi and thanks for your info.I already made this configuration but without any good results.On the USG connected to multicast server i see IGMP status correctlyBut on the other USG the same tab is empty.Do i have to create a policy route also on the USG#2?Because sniffing packets on the USG#2 i see Membership query from 192.168.11.1 (IP address of USG#2) and after Membership report group from 192.168.11.55 (Client PC) to 239.0.0.1 (igmp ip class of multicast server) but this response doesn't reach multicast server.0

Hi @piero
In my environment additional policy route rule is unnecessary.
And it is working without problem.
On USG#1
On USG#2
I will send you private message for check this issue more details.

I have had the same problem with the same network topology. I get unicast routing but not multicast. What is the solution?. Thanks and good week.

Hi @ GuillermoBartolome,
Can you share some information with us;
1- Did you configure as above ? In your case you need to create VTI interfaces with IGMP Downstream.
2- For multicast routing, you need to create a range address object as in the following screenshot;
(reference URL: https://en.wikipedia.org/wiki/Multicast_address)
3- Then, you need to create policy routes for 2 side. For that please set VTI interface as next hop.
Best regards.
