    USG support IGMP proxy over VTI IPSec VPN tunnel interface.

    But it's limit on what's kind of multicast application you using.

    Hi @GroundOPSADS ,

    It only can be used in VTI interface, the VTI interface can transmit multicast traffic in a VPN tunnel.

    You need to set up the application scenario from “Site-to-Site” to “VPN Tunnel interface.”.

    Please have a try and kindly share your test result    😀


    VPN tunnel interface at “CONFIGURATION > VPN > IPSec VPN > VPN Connection”

    Create a VTI interface at “CONFIGURATION > Network > Interface > VTI”
