Hello,
I'm using ipfilter v4.1.8 in FreeBSD 6.0-REL to protect my
laptop while traveling around or at home when I'm connected
with Wi-Fi to the Internet.
At home I'm accessing my access point only with WEP security
and ipfilter / ipnat works fine and as expected.
In my office recently we installed an AP as well with WPA-PSK security
and when I launched it for the 1st time it did not work and I was
thinking in a some how missconfigured AP or W-LAN interface in my
laptop. After hours it turned out, that it works fine but only
when I remove the ipfilter with '/sbin/ipf -D' or if I remove the
entry for ipfilter from the boot file /etc/rc.conf.
It even does not work with a very simple /etc/ipf.rules file like:
#
# No restrictions on Wi-Fi
#
pass out quick on iwi0 all
pass in quick on iwi0 all
#
# No restrictions on Loopback Interface
#
pass in quick on lo0 all
pass out quick on lo0 all
The Wi-Fi itselft comes up after booting with a script:
#!/bin/sh
#
kldload -v wlan_acl wlan_wep wlan_ccmp wlan_tkip
ifconfig bge0 down
ifconfig bge0 inet 222.222.222.222
route delete default
wpa_supplicant -B -i iwi0 -c /etc/wpa_supplicant.conf
sleep 1
ifconfig iwi0 inet 193.31.10.34 netmask 255.255.255.224
route add default 193.31.10.58
The interface iwi0 gets associated fine without any problem
but traffic does not go out.
I have the following kernel mods loaded:
# kldstat

12 1 0xc2d1e000 7000 wlan_ccmp.ko
13 1 0xc2d25000 4000 wlan_tkip.ko
What could be the problem with the ipfilter?
Thx
