Qemu networking help

[Allie Daneman]

So I recently installed Qemu w/XP on my 4.1 box and am having a bear of a time 
getting pf and the networking going. I've tried the undeadly howto and another 
on the Qemu forum to no avail. Can anyone share their qemu ifup script, how 
they run it, and the important parts of their pf.conf to get it running ? Thnx 
in advance...
