Hausen from comment #7) >You must not put IP addresses on bridge member interfaces. All addresses m= ust go on the bridge. > This is documented in the handbook page for bridging: > https://docs.freebsd.org/en/books/handbook/advanced-networking/#network-b= ridging >> If the bridge host needs an IP address, set it on the bridge interface, = not on the member interfaces. > I don't know if this already fixes your problem or if there is still a bu= g preventing multicast from working, but your setup is definitely wrong if = you have an IP address on a member interface. So that I am 100% clear, are you suggesting the following: 1. Physical interface, say, igb0 exists and passes traffic on the lan 2. User desires to create bridge for use with bhyve 3. User/bhyve accessory software creates bridge, adding igb0 as member and tap0...N for M Virtual machines 4. User should REMOVE IP from igb0 and ADD IP to the bridge (does not have = one by default) ? > Kristof Provost has confirmed that putting an IP address on a member IF b= reaks multicast! Can you point me to this? Regards --=20 You are receiving this mail because: You are the assignee for the bug.=
