VirtualBox bridged network with FreeBSD - no route to host

J

Jakub Siroky

Hi all,

I've been fighting with following setup with no success several days: 10.3-RELEASE-p12, virtualbox 5.1.6 from pkg, two nics and bridged nic on vbox and internal nic.

There is "no route to host" when pinging to vm, and there are no replies from inside of vm.
Arp shows the correct values. Nat mode of Virtualbox works, but I cannot connect to SIP provider via two NATS - first on VM and second on public nic.

Thank you, any help would be appreciated.

freebsd-version

10.3-RELEASE-p12

For anyone interested: when I recompiled virtualbox from source the bridge mode started to work, hurray!

Ehm, apparently building VirtualBox from ports also upgraded your FreeBSD from 10.3 to 11.1.
 
Again, after pkg upgrade it stopped working:
