I'm trying to set up the vagrant lucid32 box
The instance network setting is NAT
the virtual box instance can ping to the Mac, but can't vice versa
here is my Mac config
lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> mtu 16384
options=3<RXCSUM,TXCSUM>
inet6 fe80::1%lo0 prefixlen 64 scopeid 0x1
inet 127.0.0.1 netmask 0xff000000
inet6 ::1 prefixlen 128
gif0: flags=8010<POINTOPOINT,MULTICAST> mtu 1280
stf0: flags=0<> mtu 1280
en0: flags=8863<UP,BROADCAST,SMART,RUNNING,SIMPLEX,MULTICAST> mtu 1500
ether 10:9a:dd:a9:43:44
inet6 fe80::129a:ddff:fea9:4344%en0 prefixlen 64 scopeid 0x4
inet 10.32.24.78 netmask 0xffff0000 broadcast 10.32.255.255
media: autoselect
status: active
p2p0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 2304
ether 02:9a:dd:a9:43:44
media: autoselect
status: inactive
utun0: flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST> mtu 1380
inet6 fe80::69ca:da35:534a:9504%utun0 prefixlen 64 scopeid 0x6
inet6 fd78:f3ab:2fb2:b8b8:69ca:da35:534a:9504 prefixlen 64
And here is the virtual box network config:
The usually method to fix the "VM session session was closed before any attempt to power it on", is to discard the saved state of the Virtual machine. To do that: 1. Right click on the Virtual Machine and select Discard Saved State.
If both the machines are in the same Virtual Network, then just turn off Windows Firewall and they will be able to ping each other. Other way is to just allow all incoming ICMP traffic in Windows Firewall with Advanced Settings. (ping request or create an exception by just enabling ping (ICMP).
It is quite obvious that when you are using NAT it will be impossible to ping host after NAT. It is how the NAT works... even if you will have real not virtual host the bechaviour will be the same.
