OpenBSD5.3/PF Settings help request

Adelin Balou
Dear Sir/Madame,


I am a student in pending Master's degree in Network and Security at
University of Valenciennes (France), I am currently encountering problems
while setting up a Firewall with Packet Filter on OpenBSD 5.3.


I wall a PC with 3 network interfaces ( xl0 : connected to WAN , xl1 :
connected to WLAN , xl2 : connected to LAN ). I need that this PC works like a
firewall. I have installed OpenBSD and setting up rules in /etc/pf.conf
(please to find attached to this mail my pf.conf file it is commented in
French, if any questions just let me know).


The problem is : The Firewall has Internet and hosts on WLAN and LAN can't
connect to internet. I don't know if my NAT and Filtering rules are not
matching. My /etc/resolv.conf has an ADSL internet Box address and DNS is
working correctly. My xl0 interface has got IP from DHCP server from the ADSL
Internet Box so no need to create a file /etc/mygate to specify the ADSL
Internet Box default gateway. The command route show shows me my default
gateway.


I have contacted http://www.evolix.fr/ one of the OpenBSD support link
http://www.openbsd.org/support.html in Marseille (France) they have read the
file but they can't find the problem. I will be grateful if you could help me.


Please find attached my pf.conf file.


I am looking forward to reading from you as soon as possible.


Kind regards,
