But the manual page just says to do: # ifconfig pflog0 up # tcpdump -n -e -ttt -i pflog0 No mention of IP addresses at all, let alone DHCP. >I also have >ifconfig_pflog0="DHCP" >in my /etc/rc.conf. > > > It's trying to get a DHCP address because you have told it to, right here. Try commenting this line out and rebooting (yes, there probably is a way to do it with rc scripts; feel free to investigate :-). Or just try "ifconfig pflog0 down; ifconfig pflog0 up" but it may try and remember your DHCP setting). --Alex
