View Full Version : Sharing ppp connection with wlan interface

September 21st, 2009, 03:50 AM
Dear all.

I'm on Debian Sid, and as Ubuntu community is being really kind helping me I'm trying to find out what's happening around here.

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
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 port 67 interval x

Here's my dnsmasq.conf file:


And my syslog on the router computer.

Sep 20 23:46:48 vinicius kernel: [ 3349.172165] wlan0: No active IBSS STAs - trying to scan for other IBSS networks with same SSID (merge)
Sep 20 23:46:51 vinicius kernel: [ 3351.704879] wlan0: Selected IBSS BSSID 0e:45:9e:94:06:07 based on configured SSID

The above goes like that forever.

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