I just don't know where else to look and what else to do. I keep getting a 403 error on all my vhosts after setting varnish 3.0

Apacher log:

/etc/default/varnish:

             -T localhost:6082 \

So, any ideas what I could be missing?

Update

Just so you know, ports:

NameVirtualHost *:8000
Listen 8000

and <VirtualHost 205.13.12.12:8000>
