pflog0 question

[Beni]

Hi all,

Does pflog0 need to get an ip-address from dhcp ? From what I can see in 
dmesg, pflog0 can't get one (vr0 does) but pflog0 seems to be up and running 
(same for pf and pflogd).

So how do I get an address for pflog0 (if needed) ? I'm using 6.1-STABLE.

From dmesg :

[...]

DHCPNAK from 192.168.1.1

In my /etc/pf.conf I have :
pass in quick on $ext_if inet proto udp from any to any port { 67, 68 }

The /var/db/dhclient.leases.pflog0 is an empty file, 0 bytes whereas 
dhclient.leases.vr0 is 730 kb.

I also have 
ifconfig_pflog0="DHCP" 
in my /etc/rc.conf.

Thanks for any help.

Beni.
