Basically, Internet connected laptop via wifi on a 10.10.2.0/24 network, laptops IP 10.10.2.252, gateway IP is 10.10.2.1. I want to put my VMs on a separate, but internet connected subnet 172.16.32.0/24 in the bhyve vms: # cat /etc/rc.conf: ifconfig_vtnet0="172.16.32.11/24" defaultrouter="172.16.32.1" # cat /etc/resolv.conf nameserver 127.0.0.1 #unbound can this sort of network config be done without NAT or a bridge, by pure routing? >Regards, >--WjW
