My firewall is not logging, /var/log/security is uttlerly empty and have been 
for over a month. And I don't get it. AFAIK everything is set up ok, so 
anyone got a clue to what I'm missing?

From my kernelconfig:
options         IPFIREWALL
options         IPFIREWALL_VERBOSE
options         IPFIREWALL_VERBOSE_LIMIT=100
options         IPDIVERT

From /etc/rc.conf:
firewall_enable="YES"
firewall_logging="YES"
firewall_script="/etc/firewall/newrules"

My firewall:
# Define the firewall command (as in /etc/rc.firewall) for easy
# reference.  Helps to make it easier to read.
fwcmd="/sbin/ipfw"
 
# Flush
$fwcmd -f flush
 
# Allow all data from my network card and localhost.  Make sure you
# change your network card (mine was fxp0) before you reboot.  :)
$fwcmd add allow ip from any to any via lo0
$fwcmd add allow ip from any to any via xl0
 
#Allow all connections from localhost and keep them
$fwcmd add allow tcp from any to any out xmit xl0 setup
$fwcmd add allow tcp from any to any via xl0 established
 
#Open for apache
$fwcmd add allow tcp from any to any 80 setup
 
#Reset all ident packets.
$fwcmd add reset log tcp from any to any 113 in recv xl0
 
# Get to the DNS
$fwcmd add allow udp from any to 193.162.159.194 out xmit xl0
$fwcmd add allow udp from any to 193.162.145.130 out xmit xl0
$fwcmd add allow udp from 193.162.159.194 to any in recv xl0
$fwcmd add allow udp from 193.162.145.130 to any in recv xl0
 
# Ping and traceroutes
$fwcmd add allow icmp from any to any
 
# Luk for <1024
$fwcmd add deny log tcp from any to any 1-1024 in recv xl0 setup

# Luk for X
$fwcmd add deny log tcp from any to any 6000-6063 in recv xl0
 
# Allow all udp out
$fwcmd add allow udp from any to any out xmit xl0
 
# Allow ICQ in
$fwcmd add allow udp from any 4000 to any in recv xl0
 
# Strangle the rest
$fwcmd add deny log udp from any to any in recv xl0
 
# Deny the rest
$fwcmd add 65435 deny log ip from any to any
