These are slightly updated instructions I've not seen anywhere else as Arno's excellent firewall no longer works out of the box with PSAD.
I noticed this morning the iptables firewall was not starting due to the fact that I rebuilt the kernel and forgot to include the relevent Netfilter modules. So I added those and rebooted. The firewall still fails, but rather that referring to the non-available ip_tables module, it now just says iptables.init[1290]: iptables: Applying firewall rules: iptables-restore: line 13 failed.
I need a firewall because I was decade long user of internet security suites on windows.
I have a network that at the moment is isolated from the internet. We are going to connect it to an existing adsl line that has a firewall,but we want to add another firewall behind it as we do not have total control over the existing firewall.

When Sperical Cow hits the digital shelves sometime in late October or early November, users will have to get used to a new firewall management application. Sperical Cow is, of course the code-name for Fedora 18, the next stable release of Fedora.
Fedora has a Firewall Configuration interface:
Does this use iptables underneath to enforce the rules?
Hello,
Today I finally decided to configure a firewall. Everything seemed to go well, but now I can't seem to send mail from thunderbird, gmail imap mail.
The port I have set for my mail is 993, which is by default.
In my firewall setting I allow both udp/tcp connections going out on that port.
I use GUFW for my firewall config.
It seems that I can still receive mail, but not send.
