Wifi hotspot (hostapd and shorewall)

Hello, all!

I'm trying to setup a wifi AP on Debian as per this guide: http://blog.mc-thias.org/?title=crea...&c=1&tb=1&pb=1 For me eth0 is the connected adapter with dhcp and wlan0 is the wireless interface.

All goes fine until I try to connect with one of my devices. It crashes at the IP address obtaining stage. hostapd with maximum logging (-dd) produces this output upon connection:

Here is my configuration:

hostapd config:

Code:

interface=wlan0 
driver=nl80211 
ssid=diss
auth_algs=1 
channel=1 
hw_mode=g

Shorewall config:
interfaces:

Code:

net     eth0            detect          dhcp,tcpflags,nosmurfs,routefilter,logmartians
loc     wlan0            detect          tcpflags,nosmurfs,routefilter,logmartians

routestopped:

Code:

wlan0           -

masq:

Code:

wlan0                   eth0

Thank you for any help. Also, if there are alternative approaches, let me know.
