+## Network issues
+If it is not possible to ssh or connect via NFS to the virtual machine, check the routing by running `netstat -rn | grep 10.10.10`.
+The expected output should be similar to:
+```
+10.10.10/24        link#15            UC              3        0 vboxnet

+10.10.10.255       ff:ff:ff:ff:ff:ff  UHLWbI          0       18 vboxnet
+```
+If the routing table does not look similar to the above, re-check the Host-only Networks adapter settings, and that the virtual machine correct adapter is selected. It might also be the case that VirtualBox requires an OS reboot before applying the routing correctly.
