However, my USG is not aware of the VLANs and is not involved in them at all. I probably should not have mentioned them. This is really a question about how the USG behaves when its acting like a switch. My switches are VLAN capable. Everything works if P3 uses a different subnet. If I try to make P3 on the same subnet as P2, ARP broadcasts don't work and that does not make sense. Still digging...

dnoyeB Ferrous Phallus join:2000-10-09 Southfield, MI	dnoyeB Member 2012-Dec-10 12:58 pm Its a topology issue. The devices are physically connected to the same segment. I can't change that. However, the VOIP device can tag its packets as part of a VLAN. The other devices cannot. This is not reflected in my question here. Its just that while I was implementing the setup that should have solved my main issue, this side issue came up because it did not work. From everything I know about networking, it should have worked.
