I do not think there is a default firewall ; in any case, I have never heard about it.
Thanks for all of the suggestions. Isn't there a *default* firewall
install when you setup a basic version of etch? If I didn't
specifically install a firewall, does that mean that there is
currently no firewall setup?
I am happy to write and work with iptables using a script from
/etc/init.d, but I thought etch might have a *default* firewall
pre-configured? Maybe not? :).
