When I add any iptables rule, e.g.:

iptables -P INPUT DROP
iptables -P OUTPUT ACCEPT
iptables -P FORWARD DROP
iptables -A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT
iptables -A OUTPUT -m state --state ESTABLISHED,RELATED -j ACCEPT

The rules work, but:

When I want to shut down the pc (or reboot) with a normal user, it just hangs...I can still "see GNOME" - the Shutdown button is "stuck". But I can shut down the pc by hitting alt+ctrl+backspace

When I want to shut down the pc with root in a terminal, it lastly says: "acpid: exiting", but it wouldn't shut down

problem occurs: I tried it on a freshly installed:
2.6.26-2-amd64 ...x85_64 GNU/Linux (my pc)
and
2.6.26-1-686 #1 SMP i686 GNU/Linux (other pc)
even with
2.6.26-2-686 #1 SMP i686 GNU/Linux (the same other pc)

Debian Lenny's

I tried a Debian Lenny on VirtualBox, without GNOME, problems the same, I must "reset" the box to reboot
problem is almost the same (when shutdown, or reboot it still hangs):
...

"Asking all remaining processes to terminate....acpid: exiting

done.

Killing all remaining processes...failed.
Stopping portmap daemon..."

and it just waits, waits

lshw:
pastebin - collaborative debugging tool
lspci:
pastebin - collaborative debugging tool

Is this a bug? What should I do if I want the pc to shut down when pressing the shut down button, and use iptables too?
Under Ubuntu, when I simply add an iptables rule, then I want to shut down the pc, it shuts down

Thank you

Firewall will never hang your computer while rebooting or shuttlingdown the box. This is something else.. Do you run debian inside virtualbox? Try updating both kernel and virtualbox software.

When I use:

"/etc/init.d/network stop"

It shuts down/reboots/logs out ok

I'm thinking about it, maybe it's an acpid bug.
I tried an Ubuntu 9.04, it works ok, so it could be Debian related

It's always up-to-date

ps.: for a moment I thought I got it work :
I append the sid repo in Lenny (in VirtualBox) for the sources.list, and installed acpid from the sid repo:
When I give a reboot command in a root terminal: It finally reboot's ok!
But, when I click at shutdown, with a normal user, it still hangs, the button looks like it's pressed, but nothing happens, even after minutes.
