так вот в сети нашел большое количество описания настройки сетевых адаптеров, но все они в основном если virtualbox установлен на винду

Re: pfSense in VirtualBox on Ubuntu

YES! I got it working after almost a week of fiddling!
Turns out the reason the WAN interface was not getting an IP is because it was not configured in the Ubuntu host. You need to make sure there is an entry in your /etc/network/interfaces file for every network card you intend to use.
Here is what my file looks like:
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).
# The loopback network interface
auto lo
iface lo inet loopback
# The primary network interface
auto eth0
iface eth0 inet static
address 0.0.0.0
auto eth0:1
iface eth0:1 inet static
address 192.168.0.2
netmask 255.255.255.0
gateway 192.168.0.1
dns-nameservers 192.168.0.1
# The WAN interface
auto eth1
iface eth1 inet static
address 0.0.0.0
Note: The static ip addresses 0.0.0.0 are so that those interfaces (which are bridged to pfsense) don't try and get an IP.
Huge thanks to Perryg!
