hi all
I have an acer laptop with ubuntu on it and I am trying to share internet with my fujitsu siemens n520 pocket loox through wifi. I have made an adhoc connection and they seem to be connected but i can't browse from my pocket pc. the command iwconfig wlan0 gives the output

wlan0 IEEE 802.11g ESSID:"myadhoc"

and i can ping
ping -I wlan0 -c 1 192.168.0.1

My pocket pc seems to be connected but i can't browse. what's wrong?

Well, you need to actually configure routing between the two interfaces before you can share an Internet connection through the machine. Have you done anything with iptables yet in this setup, or have you only setup the Ad-Hoc network between the two devices?

well I don't know much about iptables. I have used firestarter wizard and configured wlan0 as lan allowed connection. To pocket pc I have used ip:192.168.0.1, dns the output of cat /etc/resolv.conf and gateway the IP of laptop wlan0 192.168.0.2

It's ok. l just had to leave firestarter on and now I can browse from my pocket pc
