Dear all.

I'm on Debian Sid, and I've been trying to serve a=20
ppp0 internet connection through a wireless=20
network. I made a small script to be ran when i=20
want to do that:

ifdown wlan0
iwconfig wlan0 essid "VinaNET" mode Ad-Hoc
ifconfig wlan0 192.168.0.254
echo 1 > /proc/sys/net/ipv4/ip_forward
/etc/init.d/dnsmasq stop
/etc/init.d/dnsmasq start
iptables -t nat -A POSTROUTING -o ppp0 -j MASQUERADE

The script goes just fine and the client computer=20
can see the wireless network but can't connect, it=20
only keeps trying:

DHCPDISCOVER on ath0 to 255.255.255.255 port 67=20
interval x

Here's my dnsmasq.conf file:

domain-needed
bogus-priv
interface=3Dwlan0
dhcp-range=3D192.168.0.1,192.169.0.100,12h

I'm not quite sure if that's an iptables or a=20
dnsmasq problem.

Thanks!
