Wrote my own firewall script. Where do I put it now? :)

[Legshot]

I've written my own firewall / masquerading script and wonder where the optimal place under Gentoo would be? Also, can I add it with rc-update to the system startup?

I've this line

try putting the script in /etc/init.d. then, like you said, you can use rc-update add script_name default to add it to the default runlevel. as for the ip_forward option, I don't know of a special way to do it in gentoo.

you can also put one or both in /etc/conf.d/local.start

good place for hdparm optimizations as well, if you need those.
