Hi,
What is Etch using as its default firewall? How do I change that
firewall's settings?
As others have pointed out, no firewall is configured by default.
Iptables is the kernel code that provides packet filtering but isn't
in and of itself a firewall; all firewall packages in linux, AFAIK,
are programs / scripts that create iptable rule sets for you. As you
AIUI, iptables *is* the firewall. Shorewall provides scripts which create
rules. Not sure what Guarddog/Smoothwall etc do but I'm guessing they do
much the same thing.
So a firewall is a "set of rules + iptables"? When is a firewall not a
firewall? :-) Or are we "splitting hairs"?
