I don’t know if i’m doing it right but I tried « -vlanhwtag » all the interfaces and I’m still having problems. Namely (as I didn’t have this information before) that all participating interfaces in the bridge itself are in promiscuous mode (and, if that is related) I cannot ssh into the host machine from any bhyve virtual machine. My goal is to be able to ssh and mount host nfs exports onto the VMs. Doing a « -promisc » on all the interfaces won’t change anything. Can someone help? Pleas find below a ifconfig dump. I'd go for tcpdump. First, check that routing is no issue. In your constellation I guess VMs Ips are in the 192.168.1.0/24 network, correct? Else make sure your default gateway does routing/deflection/icmp-redirection. Then watch 'tcpdump -n -e - s 150 -i bridge0' on the host and the like inside your VM (vtnet?) Start with ping and check if ARP is working. Also 'arp -a' on host and VM provides fundamentally information to find the problem. If ARP and icmp (ping) work but TCP (ssh) not, it's PMTU or offloading related most likely. -harry
