Here's the steps I take when setting up virtual domains under FreeBSD:

First, I select a free IP (as you've done with 199.1.2.100).  I then
add a line for this ip to /usr/local/etc/rc.d/aliases.sh formatted as
'ifconfig <interface> alias <ip_address> netmask <netmask>'.  For your ip
address, this could look something like (assuming vx0 int):

	ifconfig vx0 alias 199.1.2.100 netmask 255.255.255.255

aliases.sh will be ran at boot time, but go ahead and make this ifconfig
active by just typing it at the command line...

Now, 'ifconfig -a | grep 100'  should show something like:

	inet 199.1.2.100 netmask 0xffffffff broadcast 199.1.2.100

After this, you simply make the necessary DNS and apache modifications to
name and point to the domain...

Good luck...
