Hi Chris,

I use FreeBSD version 8.1, the host OS is Ubuntu 10.10. The host OS could connect to the Internet correctly. This host uses a private IP address. Yes, I allowed the VM software to install the bridge adapter now, when booting there are some msgs "no DHCP offers received". Actually I am a little confused where the DHCP server is, do I need to install a DHCP server? Also, do I need to add that line "ifconfig_le0/pcn0="DHCP" in /etc/rc.conf?
I am also don't understand how to set the static IP address since when setting a static IP address, we should have a router interface address, right? But now it's only a virtual machine running on a real machine, how can we do that?
Thank you so much for your help. I am sorry for bring you so much trouble.
