Hi all, this is the first time I tried to use bhyve. This is 12.0-RELEASEp3 and vm-bhyve 1.2.3. My hosting provider hetzner.de is giving out subnets which are=20 routed through the main ip of the server, so if my main IP is xxx.xxx.xxx.63 the subnet yyy.yyy.yyy.224/28=20 is routed as if it was "behind" the main ip xxx.xxx.xxx.xxx. I first didn't know that and tried the solution mentioned in the=20 vm-bhyve wiki, usiing a bridge and adding the network card (em0)=20 to it, which didn't work. Since I never used byhve I wasn't to sure where the error was, but=20 after asking Hetzners support and getting info about their setup I=20 guessed it was the bridge. So I just removed the interface from the bridge and added the=20 subnet to it. This seems to work, even without adding a static route, netstat -r=20 gives yyy.yyy.yyy.224/28 link#3 U vm-public after a reboot (vm-public is the name of the bridge), and now the=20 bhyve VMs have network connection. I'm still a bit puzzled if using a "bridge" this way is a good=20 configuration. And why do I not need a gateway address? Yeah, my IP knowledge is=20 a bit thin ;) Thanks for any comments, Mathias --=20 Mathias Picker=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20= =20=20=20=20 Gesch=C3=A4ftsf=C3=BChrer Mathias.Picker@virtual-earth.de virtual earth Gesellschaft f=C3=BCr Wissens re/pr=C3=A4 sentation mbH http://www.virtual-earth.de/ HRB126870 support@virtual-earth.de Westendstr. 142 089 / 1250 3943=20=20=20=20=20=20=20=20=20=20=20=20
