I've verified from other hosts on the network that my packets are being sent, that I am able to receive packets (as long as I didn't send them), and that I get the same behavior when using vfio-pci with both e1000 and vmxnet3 (emulated in VMware). Is there some built-in source MAC filtering that I'm missing? Or do I have to enable loopback mode? Thanks, Dominic
