DSL Tips and Tricks :: automatic dsl firewall

Hi at all.
Damn Small Linux have a program called r.c.firewall in the mydsl menu,in the Net subsection.
Is a powerful and very robust firewall,but by default is needed you launch this program every day or however every pc reboot.
To make automatically the start of this firewall,open the .xinitrc with beaver and add "start_firewall".
In this mode,the firewall starting automatically when pc is start,when open fluxbox,for highest and continuos protection of your pc.
The default firewall shell is aterm and when fluxbox is starting,display the firewall program with bad color,because is transparent.
To resolve this beauty problem,go to the /usr/bin directory and open the file "start_firewall" with beaver.
The default configuration is:
"rxvt -rv -T "rc.firewall" -e sudo /etc/init.d/rc.firewall"
delete "-rv" and replace with "+tr".
Save it and close beaver.
Now the firewall shell is black with white characters,good and beautiful color for this program.
Goodbye and good dsl at all.
Excuse-me for bad english but i'm italian!

WHAT !  A FIREWALL, WE DON'T NEED NO STINK'IN WALL!

(Just joken of course  . I just could'nt resist)
I haven't used virus protection or a firewall since i begin useing linux a year or so ago.

I like your suggestion but you normally cannot edit /usr/bin especially if its on a cd.

I'm sure you can without having to remaster. Can someone suggest a way around this?
