Hi. Sorry for my bad english.
I'm experimenting with a WinXP host and a virtual network using VirtualBox
126.96.36.199127; I'v created 3 virtual FreeBSD 8.0 PC.
The REAL PC is connected to the internet with an ADSL router; real router has a
static IP 192.168.0.1; real PC NIC address is 192.168.0.2.
The first virtual PC works as a gateway between two nets with this
- 1 NIC in NAT - DHCP - assigned addres 10.0.2.15 (the standard IP
automatically assigned by VirtualBox 3.1.2)
- 1 NIC in Internal Network - IP 172.16.1.1/24
- 1 NIC in Internal Network - IP 172.16.2.1/24
This configuration lets me go on the internet and gives me access to the
clients on the 2 nets.
Both virtual clients ping the others virtual PCs and both clients can access
FTP area of the others virtual PCs.
From the virtual gateway I can access the real host webServer (which is not
This is (part) of the gateway's /etc/rc.conf:
#this is my real ADSL router
ifconfig_em1="inet 172.16.1.1netmask 255.255.255.0"
ifconfig_em2="inet 172.16.2.1netmask 255.255.255.0"
This is first "client"'s rc.conf:
ifconfig_em0="inet 172.16.1.2netmask 255.255.255.0"
My basic idea is to create a virtual network which uses real PC ad it's ADSL
router (I'm working at home) only to allow my virtual gateway to access the
internet (which is possible).
I'm not interested in comumunicating with real PC. I'd like to simulate a Small
Office situation with a gateway, which should be the only one with an internet
access (later I will, maybe, configure a firewall, a DNS server, a DHCP server,
a NFS server, a Samba server ... and so on); the client virtual PCs should go
on the internet through the gateway.
The problem is that virtual gateway accesses the internet, but le virtual
This is the output for netstat -r from virtual gateway

172.16.2.0 link#3 U 0 0 em2
172.16.2.1 link#3 UHS 0 0 lo0
I think that 10.0.2.2 is the address of VirtualBox DHCP.
I've tried to configure em0 as a NIC with a bridge, but I've failed (probably
for a fault of kowledge aboud bridges).
Thank you for any help.
