Thanks for helping.

This tutorial says to pass ppp0 as the argument to -o.

Anyway, here's the syslog output for your correction on the routing computer.

no expert, but i think you masq the wrong conx?

iptables -t nat -A POSTROUTING -o wlan0 -j MASQUERADE

also

tail -f /var/log/syslog on the routing pc and see what dhcp is saying.

Dear all.

I'm on Debian Sid, and I've been trying to serve a ppp0 internet connection through a wireless network. I made a small script to be ran when i 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 can see the wireless network but can't connect, it only keeps trying:

DHCPDISCOVER on ath0 to 255.255.255.255 port 67 interval x

Here's my dnsmasq.conf file:

domain-needed
bogus-priv
interface=wlan0
dhcp-range=192.168.0.1,192.169.0.100,12h

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

Thanks!
