Genwall for N900

Hi all,

This application was born out of boredom due to the loss of DSL connection.
I used the N900 as my router, the poor bandwith forced me to do local stuff on my computer like programming.

In 2012 the version 1.0.0 took part in the coding competition. http://wiki.maemo.org/Maemo.org_Coding_Competition_2012

Genwall started in principle as an iptable firewall script generator. These days it can do a bit more.
It is very useful if you want to route or forwarding to another network.

The generated firewall script is based on this example:
http://www.debuntu.org/iptables-how-...et-connection/
There are the same chains defined, but genwall you can choose logging or not.

- creating connections with Wlan-ad-hoc, USB, BT
- you can activate forwarding from internet from and to any device
- set your firewall script, open ports, forwarding ports
- gives network and iptable informations
- you can modify start scripts or the firewall script by yourself with an editor
- it can read syslog file


requirements:
- you need to start application as root
- sysklogd (only if you want to enable logging)


All files genwall creates are in "/home/user/.genwall/".
[local->basics]
"gen" button = generates firestart.sh
"start" button = runs the script
"stop" button = generates and runs firestop.sh script

First steps would be:
Choose your "WAN-device" (local->basics) and your "LAN-device" (for/out->forward)
and generate your script. After this you can start it to set the firewall up.

Solid scripts you will find in /opt/genwall/
These script are based on forum members and applications
maybe you want to add something

bt_on.sh (route->BT: start button)
bt_off.sh (route->BT: stop button)
hotspot.sh (route->Wifi: adhoc button)
hotspot_off.sh (route->Wifi: adhoc button)
wifi.sh (route->Wifi: wifi start/stop button)
ssh-status.sh (local->SSH: start/stop button)
usb_on.sh (route->USB: start button)
usb_off.sh (route->USB: stop button)
usbmodule.sh (route->USB: module 3x button)
