Hi folks!
Just another problem:

boot process:
....
net.inetip.forwarding:0->1
starting network
working in ddial mode
using interface: tun0
no IP adress found for tun0
/etc/pf.conf:37:could not parse host specification
pfctl:syntax error in config file: pfrules not loaded
starting system logger
starting ....


this is my /etc/pf.conf (not the original pf.conf, deleted all german 
comments):

### VAR ###

Loop = "lo0"                  

table <NoRoute> { 127.0.0.1/8, 172.16.0.0/12, 192.168.0.0/16, !$IntNet,

line 37 is this:

I already used google to find a solution, but I couldn't find anything 
which is useful to me.
Thanks for your help.
