This is a micro HOWTO, perhaps someday to be longer about how to turn your N900 into a wifi hotspot. In other words, you connect to the Internet via the GPRS (telephone data) connection, then share your connection via wifi with everyone within reach. :)
You will need a kernel with NAT modules. I have one available. See my installing my custom kernel to get a usable kernel if you don't feel like building one. The 2.6.28-omap1-jebba6 kernel is known to work (2.6.28-20094102.3+0m11).
 iptables / iwconfig
You need iptables and iwconfig to use this script. Thankfully they are in the extras-devel repository:
apt-get install iptables wireless-tools
Create and run this script:
#!/bin/sh # Run this script to share your Internet connection. # Activate your gprs0 (fone data) connection with the GUI # Then run this :) set -x # insert masquerade module sudo modprobe ipt_MASQUERADE # flush old rules sudo iptables -F sudo iptables -t nat -F sudo iptables -t nat -A POSTROUTING -o gprs0 -j MASQUERADE # forward IPs echo -n 1 | sudo tee /proc/sys/net/ipv4/ip_forward sudo ifconfig wlan0 down sudo iwconfig wlan0 mode ad-hoc sudo ifconfig wlan0 up sudo iwconfig wlan0 essid freemoe sudo ifconfig wlan0 10.0.0.1 netmask 255.255.255.0 up
 Set up Guests
Right now the above doesn't provide DHCP or DNS services, which means you have to set up a static IP and set up DNS in your clients. Just use a static IP from 10.0.0.2 to 10.0.0.254, use 18.104.22.168 for your DNS servers, and set your gateway to 10.0.0.1. You'll need to set your client in ad-hoc mode and use ESSID freemoe.
