I have installed shorewall at late last night and i forget it today i've restart my server now i am not able to connect it :D is there any way to connect shorewall ?
If you have locked yourself out then you'll need to have physical access to the machine and log in using the console.
You may also be interested in a linux based firewall such as IPCOP. http://www.ipcop.org or http://sourceforge.net/apps/trac/ipcop/wiki, but this will turn the machine into a dedicated firewall.
