you have to use ipmon(1M) to watch the logged data.

Hi!

I tried to get a log from ipfilter, so I can see

-)what has been blocked and
-)how packets have been NATted.

I tried following the instructions, found in

http://www.linuxtopia.org/online_books/opensolaris_2008/SYSADV3/html/faa
vk.html#gdfwa

But I don't get anything in the log.

What I did:

a) created ipfilter-rules with logging:
r...@kunde003-wan:/etc/ipf# cat ipf.conf
# Non-service programs rules
# Global Default rules
#pass in proto udp from 10.2.2.2 port != 53 to localhost
pass in log quick on wan3001 from 213.172.123.138/32 to 213.172.115.4/32
pass in log quick on wan3001 from 120.0.0.0/24 to 213.172.115.4/32
block in log quick on wan3001 all

b) created NAT-rules
r...@kunde003-wan:/etc/ipf# cat ipnat.conf
map wan3001 120.0.0.0/24 ->  82.100.214.138/32

c) checked that the rules got activated:
r...@kunde003-wan:/etc/ipf# ipfstat -io
empty list for ipfilter(out)
pass in log quick on wan3001 from 213.172.123.138/32 to 213.172.115.4/32
pass in log quick on wan3001 from 120.0.0.0/24 to 213.172.115.4/32
block in log quick on wan3001 all

d) checked that the nat-rules got activated:
r...@kunde003-wan:/etc/ipf# ipnat -l
List of active MAP/Redirect filters:
map wan3001 120.0.0.0/24 ->  82.100.214.138/32

List of active sessions:

e) touched /var/log/ipfilter.log:
r...@kunde003-wan:/etc/ipf# ls -l /var/log/ipfilter.log
-rw-r--r--   1 root     root           0 May  7 15:01
/var/log/ipfilter.log

f) told syslog to log into /var/log/ipfilter.log:

r...@kunde003-wan:/etc/ipf# grep ipfilter /etc/syslog.conf
local0.debug                                    /var/log/ipfilter.log

g) restarted system-log:
r...@kunde003-wan:/etc/ipf# svcs -a | grep system-log
online          9:30:36 svc:/system/system-log:default


I assume that I have to tell ipfilter to generally log to facility
local0, but I don't know how?
Does anybody have an idea, what I am missing to activate logging for
ipfilter?

Thanks,
Kai
